Aleksey, I'm not trying to be rude, but other than maybe your uncle, did have a chance to try randori against assorted judo yudansha? I think judging judo by how you do against the mudansha might not be very helpful in evaluating judo. I wasn't too impressed with aikido myself until I got a chance to feel a yondan's technique.
It might be a good idea to try being defensive (being centered, negating throws)against a few decent judo yudansha. The last time I tried that, I became an ashiwaza test dummy. Luckily, I had plenty of experience being kicked in the legs.
