Welcome to the Photon world! Hope you are enjoying it so far.
My track history was Stock to CM7 to CM9. Im guessing that you ran CM7 on your EVO, i did the same. If youre use to CM builds.... then its hard to get away from them. give CM9 a try, and if its too much of a change for you, then CM7.
I would suggest either CM7 or CM9. The current CM9 build is plenty stable, fast and smooth. I have battery life that will last me the day and thats all i need.
The CM7 build is very stable also. My brother in law and sister run it on their Photons with no complaints.
Welcome again and glad we have another photon among the world.
Life, live it and love it; its that simple.
