I've always liked bigloo. It's probably the most pragmatic of the schemes in my opinion. It never gets the attention that chicken and gambit get, though, and I've always wondered why.
Oh, right, I forgot about that one. As I remember, it's a good recommendation.
I'm guessing it doesn't get much chatter due to INRIA being not very good at promotion of the stuff they do, and Bigloo doesn't have the academia-industry-matrimonial push that e.g. Pharo has received.
