Loved both growing up. Maybe too much.
Enough to write some Wookieepedia and Memory Alpha articles, lol.
But not enough to write any awful self-insert fan fic or own any Starfleet uniforms. (Let's ignore my lightsaber and my combadge ... they're just mancave shelf decorations, not fashion accessories!)
But as a "mature" adult I've found my interest in both of these things waned. Because on-screen entertainment has suffered a serious decline in quality over recent decades, and those two franchises have both been defaced and diluted far too much for me to enjoy watching them.
So sci-fi literature is where my interests are found, and it turns out that the bulk of Star Wars/Trek "literature" is held to rather low and juvenile standards which are (to my tastes) just as unappealing as the vandalized garbage on screen.
I guess the short answer is I love what those shows used to be.
