If you search on the forums you can find several similar questions posted. There's no definitive list of the type you'd like, though.
You don't say which device you have. I have a c700 and a c760. I use the 760 day to day and have Cacko 1.22lite on there. Its config rarely gets touched. The 700 I use to see how the other ROMs are coming along and whether any of them are mature enough for me.
Even if you don't have the luxury of two Zs, I would recommend you flash some of the alternative roms for yourself and see which you like. Also, read the various forums for each of the roms to get a feel for the types of issues each has.
Mike.
