You mean not better than 8.1.2 or 8.1.1? To be honest, I have not seen any difference from 8.0, 8.0.2, 8.1 and 8.1.1. (never installed 8.1.2) If there was then I would say 8.1.1 maybe was the best. Jury still out for 8.1.3.
Yes, I meant not better than 8.1.2 .

Looks like performance is significantly better on my 6. Scrolling on the homescreen / opening folders, etc. is much more fluid than 8.1.2.
I haven't noticed any differences.
