Beam and Grin
I don't know much about all the other grudges you have with theymos, but Beam vs Grin dilemma seems quite obvious, as in - there isn't one. Grin doesn't have a "CEO", no premine, no dev tax. Definitely more "cypherpunk" project of the two.
Ya, Beam is cool and their software appears more polished than Grin, but I just couldn't get past the founder's reward.
