Lightsabers do more damage.
Including to your own anatomy if you're pointing them in the wrong direction. Too dangerous.
Plus, phasers have stun settings. Not only is that ethically preferable, but do you really want to be inundated in lawsuits from a bunch of people whose arms you've cut off? Or look at the flip side: since you wouldn't be the only person armed, would you rather endure brief unconsciousness or amputation?
Artoo carries all the sensors I need.
But he can't be folded up and carried on one's belt.
Star Wars ships can land.
Takeoff and landing are by far the most hazardous actions peformed by any spacecraft, aside from combat. They're also time-consuming, and you probably have to pay hangar fees. Beaming is faster, safer, and pedestrian-friendly.
Everybody speaks Galactic Standard.
Except for Wookies, Hutts, astromech droids, Rodians, that guy whose arm Ben cut off, etc., etc. And yet they all seem to understand each other. Either they have some kind of translator implants, in which case the only difference is one of presentation, or they all have to learn one another's languages the hard way even if they don't speak them, in which case there's a lot more studying involved than in Trek.
What do you think "'droid" is short for? Alouisciousdroid?
Except that most "droids" are not actually androids (a word that means "human-shaped"). C-3PO broadly qualifies, but most don't.
Overrated when you own your own ship and can go anywhere you like.
But there's money in the SW universe, so presumably it costs a lot more to buy, maintain, and fuel a ship, as well as paying any necessary license, berthing, and customes fees, than it does to say, "Computer, run program."
Besides, at least Trek holograms have full color and opacity and don't constantly have scan lines sweeping through them. The technology to cross the galaxy in days and they can't make a hologram that looks better than a 1950s TV transmission?
