I have both TT01 and TB01. TB01 is obviously better with metal shaft and oil dampers. I'd say TB02 is the next generation of TB01 so it would only be better. Of course you can upgrade your TT01 with many stuff but if you want just to play with your assemble kit first TB is better.
I don't have TA05 so I can't really compare them. But it is a belt system instead of the shaft system and people say it has better control and stability.
