You should try the stargate series next if you haven’t. They supplanted Star Trek in my pantheon. There are also some time travel series more recently that are also quite enjoyable; Travelers and Continuum.

Travelers definitely has a very distinct "seat-of-your-pants" form of plotting, though, that can seem inconsistent if you're used to something more consistently planned in advance like Babylon 5. Two big changes during S1 also made me bounce off it.

I won't claim my taste is universal: it's just something to be aware of.
