For the original Star Trek, that's just the way actors were told to act back then.  Everything was overly dramatic and hammy. Thankfully we've gotten away from that.
They aren't even competing. SW is a space opera action film series while ST is more interested in showing a version of the future. And exploring more philosophical questions in a campy way even though this sometimes falls flat. 
The only thing they have in common is that they take place in space and have star in their name. >

Yes but that is where they both fall flat. Star wars. Too much emotion. Star Trek . No emotion. >

I'm definitely a SW guy and not a ST fan. But how can you form a single-lined opinion on SW acting when it can be as good as Andor / Rogue One and, at the same time, as catastrophic as Obi Wan / Book of Bobba Fett / Solo?
