Okay, here’s how it boils down: Both.
I grew up watching the old Star Trek with Kirk, Spock, McCoy, Scotty, and the rest, so I will always have a love for the series. Some episodes were great, others were mediocre, but everything was a lot of fun! Spin-off series were watchable, but didn’t have the chemistry that TOS did. The movies 2-4 were brilliant, and a couple of the TNG movies were great (Insurrection, First Contact). So, yes, I do like Star Trek, but I’m far from calling myself a “Trekkie.”
Star Wars (4-6, mind you. 1-3, in my opinion, do not exist) was simply magical. It’s not science fiction, it’s a western set in outer space. It’s the hero’s journey, a classic morality epic, and one of the best set of films ever made. Han Solo is brilliant, Leia is hot, and Darth Vader is the embodiment of evil!
That being said, they both have their merits, but they are apples and oranges. I love both, but it just depends on which flavour I’m more in the mood for at the time.
