technically your stock rom is still custom, but its definitely to your liking. ive found that so far, my stock ese81 rom is the best compared to SS v3.0 and CyanogenMod 18.104.22.168. these roms are so kick ass, but theyre just not up to par with what i like. id rather get my stock rom to how I like it. my stock rom is overclocked with chevyz 1.1GHz kernal and so far it seems smoother and faster then the both ese81 roms ive tried. and faster than the ese53 ones too. so for the people that want to know which is better between stock and custom. id go with stock, then you can customize it.
