Handbreak encoding help - eviltoast

This might not be the best place for this question but I honestly can’t think of another place, but if you know of one please let me know. But I figured someone here might have the experience I’m looking for.

I own the discs for various Star Trek series and everything Stargate. What I’m trying to do is use handbrake to encode them to put them on Plex. But everything I try, it just looks worse. Is there a repository of like recommended settings for various media?
