TA06 can use very low profile shells (front shocks are horizontal). If you use LiPo TA06, should have better left/right weight balance. I don't like the way the battery is inserted from the bottom though - looks like a toy, and changing battery is not very convenient.
Sakura Zero S parts are more available and cheaper. Quite a few KWS shops carry a full range of the parts. TA06 is a bit uncertain. Overall, Sakura Zero S should be a cheaper car to run.
