Tatar is more transition, possession. Zacha is more about how he finds open space and his wrist shot. Johnsson is a mix of the two, with a touch of pest.

Yep. Tatar is, IMO, the best of the three, but his salary would cause trouble for the next season. Johnsson seems to be more well-rounded and much better defensively than Zacha, but Zacha is an RFA at the of his deal, (Maybe the Panthers could give him another bridge deal) and has higher potential when he hits his stride. It's tough, but I'd be happy with pretty much any one of the three.
