I have used almost every rom and the rom i like most is first of all SUPERLUMINADAD.
I like this ROM because its compact, no crappy apps installed and and takes very less space for installation and my favorite - no network messages, cause tatadocomo gives crappy register to yahoo popup messages all day when we move from non network to network areas.
Currently i am using kitkat rom which I already am enjoying much, good battery backup, good response time, good features, no crappy apps and takes very less space for installation.
I tried SAMFlare but I am not a big fan of samsung UI so gonna say I dont like it much cause there are several unwanted apps that you dont want to use.
Other roms I tried have bugs so I dont wanna talk about them so I am skipping them but if you really love customization then you should install and run these two roms. They are best roms till date.
I like less apps in my rom , tweaked and deoxed. I use xposed installer and use GRAVITYBOX plugin and xthemeengine to customize my phone. GravityBox gives you greatest features in rom rest you can use xthemeengine to change framework and I think thats all you expect from a rom. So thats my opinion. Peace
