For my buck it's gotta be ClassicBoy for performance & stability. Faster N64 than retroarch and gamepads are easy to set up. Uses PCSX-reARMed and Mupen64Plus plugins. Although it doesn't have a cool, graphical game picker, be sure to check it out.
Update:This Version of RetroArch Works great with Gamesome.
Using Live Channels with HDHomerun Prime and Live Channels goes back to the home screen after every hour. I can't seem to find a way to fix it.
Edit: /u/drhill80 has a forum post on Silicondust's forums outlining the issue. It appears that it's across hardware:
