I love the one where they go back in time and They’re literally the Roswell aliens and as soon as Quark can communicate starts trying to scam the humons
I find TOS hard to compare to the others just because it was the trailblazer, it launched a franchise that is still going strong 60 years later. I'm slowly making my way through Enterprise, the theme song is out of place obviously, but its been enjoyable so far.
