Hmm, most of what we have here in this thread is pretty subjective. Unfortunately the answer to who has the fastest ROM will differ depending on who is using the ROM. Without objective data (benchmarks) you really won't find out until you use each ROM and judge for yourself.
That being said, research each ROM (in their respective threads) and experiment.
When you find the one that is fastest to you....stick with it and give feedback to the chef so that it keeps getting better
Good Luck!
