Looking for a 4.3 that's more stable than Omega topic

I'm been running Omega 4.3 ROMs for the last couple of weeks, having moved from a stock ROM. Both versions that I've tried (v18 and v19) have been pretty unstable - i.e. prone to spontaneous reboots. I always do a full wipe before flashing a ROM, but it doesn't make any difference.
Has anyone got any recommendations for a good, stable 4.3 ROM?
