well, first are you sure beeing on GB kernel? because CM10 works also on froyo and installing CM10 doesn't upgrade the kernel, you have to do it manually.. sorry if I ask for that but I couldn't understand if you are sure beeing on GB... Anyway, I would prefer tezet's rom because it appears to be better and surely it's more updated... personally I like very much endless's mod so I'd go for tezet's rom with endless's mod BUT, as the mod is quite old, I can't assure you it's still working on latest from tezet! In case it doesn't work you just need to perform a full wipe...
