I'm using CMYLXGO's. It's a good build, but since it's based off of Desire HD instead of just the Desire, there's more animations with the flip clock and fading in/out of screens so you'll see some lag when trying to multitask.
But you barely notice it unless you're extremely picky about performance. 90% of the time, it's smooth and error-free. No HTC-sync though.
