my favourite is Podbot2.6mm, just because i've always used POD and the other ones scare/confuse me, i'm also looking forward to RACC because PMB's technical stuff on his website looks cool, even though it could just be some claptrap he made up

the best for DOD is Shrikebot, because its the only one on Bots-united so i don't have to worry about offending the Sturmbot guys , those idiots
