Come one now.
1. Under his guidance Orochimaru Sasuke....
You can't class him as a teacher when he was trying to steal his students body, wtf? Orochimaru didn't teach Sasuke Cursed Seal. It was something Orochimaru was just testing out on him putting his life at risk, also implanting himself into his student. Thats a good teacher? Sasuke Only learnt Chidori blade, Kirin an lighting Shurikens, thats it. Sasuke had that kind of speed before as shown in his fight against Gaara in the Chuunin exams.
And since when did he learn any 'Seals'. Correct me if I'm mistaken but I don't remember Sasuke using any form of seal, ever...
2. Under Tsunade's guidance Sakura....
You can't really but that last point in. It's been rumoured to be Sage Mode but it could just be a Creation Rebirth Technique. Overall this does NOT make Tsunade a better teacher then Jiraiya. Sorry but there's just no contest here, Jiraiya raised Naruto as the better ninja.
3. Under Jiraya's guidance Naruto....
You summed it up as if Jiraiya did nothing for the past 3 years with Naruto. Naruto grew so much that even Itachi had to acknowledge it, not Sakura. His skills already are Jounin ranked. He was beyond Jounin level and took on S-Ranked Ninjas, are you forgetting about Akatsuki? Jiraiya tought him how to use his Chakra more wisely and effectively. A little speed bump? Naruto never had much speed from the get go, Jiraiya increased that even more over the years. His taijutsu also increased since in part 1 he'd always span shadow clones senselessly as shown when he fought Sasuke. Also under Jiraiya he learnt how to use his Clones more wisely then before, to the point where at sometimes he was almost able to best a sharingan user.
The way I see it, you've listed everything about Jiraiya very unfairly. You've listed things which Jiraiya CAN'T teach.
Jiraiya could only help Naruto so far with gaining control with the Kyuubi. That was Naruto's personal struggle which only another Jinnchurki could help with NOT ANY of the Sannins.
Jiraiya even made preparations for Naruto if the Kyuubi got out of hand by making a chakra supressing seal for him.
Jiraiya couldn't help Naruto with his Nature Manipulation. His Chakra type WAS NOT wind, it was fire and earth. There's nothing he could have told Naruto about it, which leads me to believe Orochimaru couldn't of taught Sasuke his lighting based moves, its something he discovered on practiced with on his own.
Jiraiya couldn't teach Sage mode, especially since he couldn't do it himself. Only the toads could teach Naruto that. Jiraiya was the best teacher there was, Period.
