That was completely groundless, Kizaru, from what we have seen had the best display at close range while Akainu's feats involves him not being able outclass or land a hit on a heavily weakened Whitebeard until when the later became completely vulnerable towards all incoming attacks. Much like Whitebeard, Akainu is a power type fighter, he mostly relies on his overwhelming power and lethality to fight. Compared to the other admirals, He's isn't particularly great as far as it concerns raw skills(Reflexes, Striking rate and reactions).
BB clearly had the advantage as far as it concerns power, he could restrain Akainu via Black Hole, he can't do anything without proper foothold no matter how great he is at close range. BB could absorb any incoming attack as Akainu's attacks aren't particularly fast to think that he won't be able to react in time. And he could handicap Akainu by nullifying his ability. I see no reason as to why Akainu would be advantageous here. If it weren't for the fact that BB is way too cocky to fight without letting his guard down, I'd say that the chances of Akainu winning are equal.
Kizaru on the other hand, could get away from the attacks range before BB could land at attack, could launch an attack of his own while being pulled which forces BB to drop the pull in order to defend from the incoming attacks, his attacks are way too fast for BB to counter, his maneuverability is too much of a trouble for him to handle, he packs just as much power if not more than Akainu. Strictly talking from the way how their fighting powers are portrayal, there isn't a single thing in which Akainu looks better than Kizaru except for endurance and lethality.
BB isn't a speedster either, you're not accounting for that. BB is the type of character who trades blows, he's a tank type character. He's not going to be constantly dodging Akainu's attacks.
So for the 3rd time I'll say it again, you absolutely don't want to be eating amplified versions of the most potent offense in the entire manga, absolutely not, its a recipe for disaster. Akainu can create attacks like this [

] in mere moments. It's not that easy.
If its a battle of outlasting a slugfest I'll choose Akainu > BB, because BB has to eat amplified version of Akainu's attacks and he will recover slower than Akainu.
Akainu tanked punches of this caliber [

BB is rolling in pain from attacks of this level [

If he takes a hit from Akainu he will feel pain beyond anything he's felt and will be rolling around in pain. Akainu will capitalize on it like the hound that he is. He is relentless.
Both are tanks Akainu simply has less openings.
Kizaru once again will have his mobility something he uses a lot from what we've seen, taken away from him. That already takes more away from his fighting style than what Akainu loses. What does Akainu even lose, that any one else fighting BB does not?
