Who makes good human figures?

Hi folks,

Sorry for the extremely basic and extremely general question, but I'm totally new to this world. Well, not totally--I come from miniature wargames and scales like 28mm, 32mm, and even 10mm. But I recently "discovered" 20mm (1:72) and am astonished at all that exists for it. Coming as I do from minis games and Warhammer in particular, I place a lot of value on really well-sculpted figures.

So, that said: who makes the best human/people/non-vehicles in your opinion?

Thanks!
