I have tried Fission, Liberty, Stock, and Apex. I like more of an ASOP build, with a touch of Blur, namely the Blur camera. I am currently attempting to tweak Apex 1.4 to my liking, but I have been VERY happy with Liberty, but when I first got my phone a few months ago, I used Fission, then Apex, and I really enjoyed Apex. After Liberty 1.0 was released, I tried it and loved most of the features, and 1.5 was an improvement for sure. There were a few things about Apex I missed, and I am trying the new release, and if I can get it setup the way I like, then I will stick with it, otherwise I will make the move back to Liberty.
I agree with what was said above. Make a backup of your phone and then test a ROM. If you don't like it, flash back to your backup and try another ROM. At present I have a backup from Stock sitting on the SD card that I can restore, and I have a backup of Liberty I can restore. Once I tweak Apex 1.4, I will do a backup of it.
