I reccommend stock 4.1.2 leak with my MODS
if you want stock touchwiz newest with MODs..
if you want a 4.1.1/4.1.2 AOSP ROM, I personally suggest ParanoidAndroid 2.5.6
and if you want AOSP 4.2 I'd would sugggest BAMF Paradigmn, but that isn't public yet, so my next is Carbon ROM is nice, Slim is great, and Eclipse is awesome if you want a nice dark theme and a great ROM..
I personally use stock kernel on touchwiz, and whatever comes in the ROMs for AOSP.
