It doesn't hurt to give a small review of the rom, though, if someone just wants your opinion. Eventually, he'll probably get around to trying them , but maybe he just wants a place to start for now. At the very least, be a bit less eilitist when you're saying for him to try the roms for himself.
Indeed. With all these excellent ROMS out there, it might be confusing at first to know where to start.
Personnally, I think Owain's ROM is the most stable out there, but still i'm using the Genesis as it is very customizable and promising and there's also the HFS which is very good looking. With Harsh 1904 kernel, they are all very functionnal and performs better than my stock G2X. It all depends on what you prefer, try them all and see by yourself
