I have used many different roms and here are a few i recommend.
Sabsa prime: seemingly the best rom for htc desire hd out of many other roms i've tried. It has literally NO bug.
The next one is jellytime. I tried its R6 release. It had blutooth problem. But they have fixed it with the new release R8 i think.
You can also try out MIUI v5 2.0 which has best optionns ever!! but its style and UI is not the best. You can try MIUI v6 3.4.19. Which is awesome (but has terrible bugs)
