Very good. I've done nearly a year of Brazilian Jiu Jitsu, and just recently started attending the no-gi classes, so I obviously prefer the gi. Explains why I do Judo, too...
But I wouldn't mind doing a no-gi Judo class. Granted, in my Jishin-Ryu Jujitsu class, the yellow - orange belts are mostly Judo throws, and since it's a self defense class, you learn it without the gi.
