I went 19 month with Touchwiz, and to be honest, it pisses me of. It ever had micro lags. Battery live is great, if you don't touch it. So I'm ready to get done with it. To see if it is a software or a hardware problem I'd like to test an AOKP, AOSP or CM based ROM.
But with one is worth trying? I shouldn't be to uncommen, as more forum post mean a better chance to solve problems. Can anyone recomend a ROM worth trying?
