well, none of them are bad despite how his newer skins may be harder for some to play with. I shared one of his newest skins with my friend who just started playing the game and he said it's almost impossible to play with it for him, not to mention it all depends on the person though.
It may be a weird choice for most of the people but i like Hamachi HD the most, with that being said; it's really easy to ready (also easier to play with HD, at least for me).
