I go through a couple of new HTC EVO ROMs a week in my quest for the perfect phone. Each one has its own unique something about it, be it stability, speed, battery life, features, or support community. Each one also has drawbacks, be it compatibility, update frequency, etc. Without a couple of more devices, I obviously can't test them all. But that doesn't mean I won't try!
So, show off your ROM. Let us know what you run, what you run it on (EVO 4G, 3D, soup can, duck), and what specifically keeps you playing with it as opposed to going elsewhere. Including a link to the developer's page would be helpful if it's hard to find via Google.
Oh, and please keep it positive. You may have left another ROM with a bad taste in your mouth, but ROMs change along with their users; issues you had may have been specific to your phone or life.
