Who wins?
Minaara wins. Base Minato's Shunshin was fast enough to react to A's fastest attack at point blank range; SM enhances your body's physical capabilities by a lot. Pa toad said Senjutsu awakens your body in many ways so Minato speed without Shunshin would increase as much as his strength, durability, endurance, recovery rate, endurance, and power of jutsu. Senjutsu increases all nin/gen/tai so Shunshin would also be increased with the already increased base speed plus both Minato and Gaara have large reserve so together it would be even larger which means even more senjutsu. So SM Minato would be faster than A or 3rd Raikage but this is Minaara who is even stronger.
Gaara can turn the battle field into all sand like under a minute in part 1, they can easily do this while flying high in the air which means Minaara can FTG anywhere and anything the sand touches so they can easily get away from anything Aytachi has plus can FTG Aytachi to him to mark him with FTG tag. Gaara's sand was fast enough to block A's drop kick from killing Sasuke, fast enough to block Sasuke's Enton spikes, fast enough to block Kimimaru's bone bullets, fast enough to block Deidara's C3 from destroying Suna, and fast enough to catch Mei who was knocked back by Wood Madara's Susanoo while also blocking 5 Susanoo's blades and this was a weakened Gaara. Gaara's power and control would be higher with Minato's chakra and skills plus even higher with Senjutsu and since it was able to block 5 Susanoo's blades before all of this I'm sure it can after all of that power up.
Minato's 4 triagram seals chakra, what's stopping him from dealing Susanoo with it? He made the seal in a way that it leaks chakra to Naruto, he doesn't have to do that for Aytachi. Minato was a sensor in base and is a better sensor in SM. Ma toad can use wind style dust cloud to hide their location while Minaara can still sense Aytachi. Minaara has the speed, power (sand tsunami), defense, reserve (Senjutsu increases their reserve even higher), and better minds (Minato and Gaara are pretty wise with Minato being the smartest of all 4 while Itachi is smart and the 3rd Raikage seems more of a brute).
Lol, team 2 mid diffs. Nobody's reacting to Ay v2 speed augmented with Itachi's chakra potency and chakra control, along with his MS and Susano/shadow clones. Not a chance in hell that Aytachi lose this
Base Minato reacted to Ay, SM increases Minato's base speed to the level it does strength and he would be stronger than Pein arc Naruto physically so you know his speed will be fast then you add Shunshin which is stronger since Senjutsu makes all jutsus stronger plus both Minato and Gaara have large reserves so Senjutsu further increases that reserve. Sasuke has better eyes than Itachi and he couldn't even see Bee (3 tails) or A's speed unless they moved in a linear movement. Gaara can turn the battlefield into sand in under a minute and fly, that means they can FTG anywhere or anything that the sand touches so Aytachi in Susanoo standing on the sand would result with Aytachi FTG to Minaara who marks them and/or kills them (SM enhanced strength+Minato's keen observation skills). Plus with frog Kata no one but Minaara would see natural energy which extends to hit its target.
A weakened Gaara used his sand to stop 5 of Madara's Susanoo's blades while also catching Mei so I don't see Aytachi's Susanoo's doing much when the sand would be stronger with Minato's reserve plus Senjutsu which power up any jutsu. Gaara sand stopped Deidara's C3 which is a village Buster, Senjutsu enhanced sand is tiers above that plus Gaara can use gold as well. Minato can FTG to or anywhere his chakra is or touches, Gaara control his sand with chakra so anywhere or anything that touches the sand can be FTG. Susanoo on the sand can have both Yata and Totsuka FTG right out of the hand just like how Edo Minato chose to FTG both Naruto and Sasuke but not JJ Obito who had them both in each hand.
itachi and third raikage win mid diff,
V2 Ay level speed to dance around gaaras sand, and susanoo to break frree of any restraints that gaara may pull,
Third Raikage durability to lol troll all of Minatos attacks
and with V2 Ay level speed added with itachis reactions and precog, tagging minato wont be an issue either,
Already counter all of these points above and the 3rd's durability can be beaten other ways, Gaara can control others by putting Sand in them so sand in the mouth or ears can work plus sealing them can work too. 4 triagrams seal chakra, Susanoo is chakra, there it goes. Then sand pyramid for Aytachi or one of Minato's seals which come from the Uzumaki clan. SM Minaara is faster than Aytachi, can FTG anywhere on the field, and can fly.
Elder toads are a non-factor, Itachi just needs to put one, or both of them under Genjutsu and then have them shoot their tongue into Minato's ear. Base Itachi has better speed and reaction then Ay in base, by a long run. Especially when he was keeping up with KCM in CQC and blitzing Bee. Add v2 speed and his reactions and speed have just gone through the roof, then give the MS pre-cog and it acts in the same way Kakashi with his Chidori needing pre-cog. Let's also not forget, Aytachi has FAR more chakra here.
Minato is a sensor in base and SM plus their chakra are connected so they'll know if anyone is in a genjutsu. Minaara is faster so they wouldn't be in a genjutsu anyways and frog song paralyzed both the body and mind so pyramid sealing ends it or sink them 200 ft underground where they run out of air. You are trying to up Itachi speed by using his fight with Naruto who used up a ton of chakra in his intense training plus used a ton in his Shunshin fight with A and use of powerful Rasengan variations on white Zetsus all before splitting his chakra into 1/13th when he made 12 shadow clones? Plus the fact that Naruto only wanted to talk and not fight and Bee was in base fighting Itachi while it was 3 tails mode that was too fast for Sasuke to keep track and needed Karin to track Bee for him while Sasuke was able to keep up with Itachi? Sureeeee lol
Minato has a large reserve (SM training requires it) and Gaara has a large reserve, it's added together in their fusion; adding natural energy to it to make Senjutsu only further increases it even more plus Ma and Pa just gathers more natural energy so they get more Senjutsu while Aytachi runs out. Sasuke had better eyes than Itachi and his MS couldn't even keep up with A's full speed which Minato in base was able to dodge at point blank range.
