Can't and won't vote.
1) It's far to early to tell. Heck, there are no PCs on the market at the moment that could handle full speed Dreamcast emulation. And there won't be any for a while.
2) 'No bugs' is hard to define. Super Mario 64 still has some unemulated effects. Yet they're seldom listed by anyone.
3) No matter who I voted for, it could demotivate the author I didn't vote for. I don't want to do that because they're both extremely talented and I don't want either to stop for a long time yet.
4) Dreamer may get picked up again and be the first or an entirely new emulator could come up and do it (Project Tempest anyone)?
