I have long held that Season 5, Episode 2 of The Next Generation is the best episode to "test" if you'll like Star Trek or not. It is a generally well-liked and well-reviewed episode, but more than that, from both a story and a character standpoint it is representative of what your average Star Trek episode is generally about.
So, my recommendation is to watch that one episode and report back.
The instances hosting active Star Trek communities didn’t exist during the previous season of Discovery, so Lemmy isn’t a great way to gauge relative interest.
On Reddit, the /r/startrek discussion thread for 4x02 has 1.1k comments and 4x03 has 600 comments while the thread for 5x03 only has about 400 comments. This seems to support your hypothesis.
