Best Way to Rip Rare DVDs?

Hey all. Amature disc ripper here. (My existing knowledge/collection mostly pertains to audio.)

I have a handful of DVD movies that are generally unavailable (limited or archive releases that are unavailable for streaming and not on any mainstream trackers).

I'm currently using handbrake, but am open to other rippers. What specifically should I do to obtain the best quality rips from these DVDs? Most are older films and shows from the 1960s and '70s.

So far, I've been ripping H.265 MKV 480p30 with passthrough audio. Is this the way? Are there any settings I should change or be aware of?

Thanks in advance.
