Default G2 support

Hi all,

i was going to buy a g2 but as i always do i wanted to know first what roms are available and how they run. Have been reading through xda and how well are kitkat roms running on the g2 ? I read that slim has troubles, is this a general issue or just rom related ? what about PA or others ?

I ussually get a new phone every 2 / 3 years so that i want to make sure to have up to date os until then.

TIA !
