Thanks for your reply !
I forgot to say that i use my phone almost for basic use sms, internet, photos, music editing , gmail etc. and of course i want to try different apps. But Galaxy ace 2 has so low memory that it barely runs even for basic use
I would like to keep jellybean 4.1.2 and try a rom but it has to be stable so i dont have to panic if something goes wrong
nusko_x mentioned Kyrillos rom and Team Canjica CM 10.1, are they stable and easy to use for a newbie like me ?
There are sooo many roms out there that i get confused
