I did numerous checkouts for PPLs transitioning to the TB10 in the 90s. It has good looks and is pretty comfortable inside.
There were quite a few downsides. It used a lot of runway on take off compared with similar Piper/Cessna types and its climb rate was poor. Also, during stall practice, sometimes it would drop a wing for an incipient spin, sometimes it wouldn't. The content speed prop on it was pretty pointless as it rarely managed 100 kts TAS. Nice to have doors on both sides, but in my opinion, an Archer beats it in every category. Generally, the TB10 is overpriced, and with its pointless CSU, expensive for maintenance.
