Kenpachi wins it easily after timeskip as it seems that his current power is way superiour compared to Hitsugaya's.
Knepachi managed to take down 3 Sternenritter, while Hitsugaya couldn't do anything against one. Of course with Bankai he might have won, but it doesn't seem that his current opponent put any effort in their fight, so going by what Hitsugaya shown so far... he can't obviously win against current Ken-chan.
Firstly it ignores the fighting styles of all shinigami (against their targets), and 2ndly (and most importantly) it ignores differences in strength between the shinigami.
It could be Aizen, Yamamoto and Kyouraku OR it could be Rukia, Renji and Ikkaku.
If Mr X is fighting the 2nd set (Rukia set), and mr Y is fighting Aizen - then of course mr Y will have trouble, whilst Mr X will easily win.
If Mr X is fighting the 1st set however, then he is obviously stronger. Problem is, as all fights were off screened (including most of Hitsugaya's fight), we have NO WAY to state that Kenpachi's targets were anywhere near as strong.
2ndly, Hitsugaya will have bankai. So his 'poor show' (not doing so bad in my opinion - look at poor mr Byakuya) against the stirnrittern is even less relevant as Hitsugaya was stripped of his most powerful moves (perhaps even 5X his strength).
As Kenpachi doesn't have Bankai, he was not stripped of any potential power. Now, sure, it looked like he had not removed his eyepatch - but as he is a close combat fighter (mainly), whereas Hitsugaya mainly uses powerful ice attacks (which the stirnrittern had copies of - if not more powerful ones due to a stolen bankai) Hitsugaya is much more restricted than Kenpachi in these stirnrittern fights.
Now, although I generally consider Kenpachi a stronger captain than Hitsugaya (I think that Hitsugaya is one of the weaker captains generally), Hitsugaya is a poor matchup for Kenpachi. Mainly as he can fly around firing moves from range at Kenpachi. Kenpachi has not shown bankai, or strong long range moves (ignoring his cutting a building in half against Ichigo, he has not shown any at all). Kenpachi can not reach or touch Hitsugaya easily.
Hitsugaya wins this in my opinion.
Well, no matter how you look at it, those who Kenpachi managed to beat weren't weasklings in any way. One of them even became Kenpachi itself with the same powerlevel, thus Kenpachi stated that he had to become stronger than he was before that fight, so how come you say that they were weak in any way?
Also, I really doubt that Hitsugaya will have any different result even with Bankai. His performance is always quite poor during all the series. Kenpachi was stronger than Hitsugaya before timeskip and it seems that now he became considerably stronger.
P.S. If you talk about Hitsu beeing stripped of his Bankai, well Ken-chan took down those three Sternennritters and had his eye-patch still intact. So he also didn't use his form of Bankai... He only seemed to use it against the Bach-wannabe guy, but still lost to him.
P.P.S. In this manga the most important thing is your Reiatsu level and it seems that Kenpachi is leagues above Hitsugaya even with his eye-patch intact, so no way Hitsu's attacks will damage Kenpachi, especially if he takes his eye-patch off.
I do not say they were weak, only that we have no clue as to how strong they were. It is an important difference.
I am not denying that Kenpachi is much stronger than Hitsugaya (I even say as much in my previous response). However, Hitsugaya is a bad matchup for Kenpachi.
