If it isn't broken don't fix it

Hi all,
i'm happily using superceleron's SCV11 from a long time and i don't notice any important bug, but i saw new roms by ALVATECH and tillaz87 (i don't like Android TV).

Have someone actually tried either SCV11, ALVATECH and tillaz87 roms? Do they have any significative upgrade over SCV11 or can i stick with it and forget about other roms?

Thank you
