Although I'd love an HD2/N1 or Evo, I have 0 issues with my TP2 stability wise. I recently installed Sergio76's Leo Cell Evo 9.1 (WM 6.5.5) with no HTC messaging client. It's very stable, pretty and runs really well. If you have a GSM TP2, I suggest you try it out. He also has a Leo Cell Pro version 9.1 which is WM 6.5 for those who prefer a more stylus friendly OS and more available RAM.
BTW, I recently installed the new version of Cookies Home Tab. Amazing stuff!
