I have a Samsung Captivate i897 and just put 4.4.4 KitKat on it. Running a bit slow. Not horrible but noticeable. How does OS version 5 work on the Captivate? Guessing slower than KitKat as OS versions usually get more enhanced?

If people had to recommend a particular OS that was the most current you could get without any real loss in performance what would it be? Found 2.3.5 was fine the few minutes I was on it. But that's pretty old. Was originally going to go for 4.2.2 but found an article on 4.4.4 so went straight to it. Curious other's opinions.

Thanks.
