Need a usable ROM

Hi Guys,

I know my question is probably provocative. But I tried out a few roms:

* Infamous
* CM 10.1 SGHT
* Nameless 4.4

But all of them are not able to play a YouTube video without freezes. Some of them developed extreme lag after using them a while or have strange issues like Nameless - which is actually not surprising at its beta.

Maybe someone can recommend a ROM, it should be Jelly Bean at least. Can live without KitKat. All I am looking for to have something a tad more up to date than the stock one and smooth.

Cheers
Holger
