Yup.
For me it's easily SW but that's because I frame the franchise on the basis of the Original Trilogy. Saw Star Wars (not A New Hope) at the Park Theater when I was 13 and kept going back. Empire was darker and as a middling teenager even better. ROTJ started the downfall as Ewoks ultimately begat Jar Jar, though at the time I really just mostly focused on the Luke vs Vader aspect.
The prequel trilogy was meh, which is really sad. I was very excited for Episode I and aspects were very good but mostly it was a bad movie. The rest of the trilogy followed suit. My nephew actually took the time to edit the three prequel movies down into about 2.5 hours of relevant material - no forced Padme-Anakin romance, no Jar Jar Binks or Boss Nass crap. It was remarkably enjoyable and still effectively told the story.
The new stuff? I think they've gone a little too "activist" in using the movies to convey the director's social leanings and it's really a pity because after the first movie there was strong potential. Rey-Finn-Kylo could have been handled well and a good story told, but that's not to be the case because apparently the story is secondary in this day and age. I really don't believe the vast majority of people had any problem accepting Rey as the hero (ine) and being the next hope for the Jedi but they just had to go overboard...
I will say I really enjoyed Rogue One as it had that OT feel. I even enjoyed Solo but that's probably because in my mind I compare it to The Last Jedi so it didn't take much to be better.
As for Trek I enjoy it quite a lot and to be honest I get more of a kick out of SW vs ST than being of any truly strong opinion. I watched the original series as a kid and grew up loving it (and sorry, but the ladies in there were amazing). The other series I enjoyed to varying degrees but never as much as TOS though the next generation was really, really good and I loved Picard as the captain.
People often forget about TOS movies that were out. Some were good, some were bad. I was a huge fan of Trek when the first movie came out but it bored me to tears. Wrath of Khan redeemed the movie aspect really well and it proceeded in hit and miss fashion. I suspect many would say more misses than hits, other than Khan. I even found the reboot series to be quite enjoyable but I'm not so much of a purist that I get offended by that sort of stuff.
Greatest scifi movie ever though was clearly Howard the Duck.
