Not really. The individual episodes were definitely better on their own, IMO.
It's been decades since I've seen any of them but, for the most part, while TOS BSG was mostly episodic in nature, there were a handful of episodes that were 2- and 3-parters that they basically put together all in one larger "movie". The "Mission Galactica: Cylon Attack" compilation was somewhat different, as it put together the excellent "Living Legend" 2-parter with the somewhat contrived "Fire in Space", two completely different stories that somehow managed to work together, albeit in a somewhat clunky manner.
One of the Galactica: 1980 telemovies was quite difficult to watch (as was most of G1980, if I'm being honest), to my recollection, as it put together elements of the 3-part pilot episodes with later episodes in the show's single and only season - causing a bit of a continuity problem with Adama's mysterious Seraphim-originating child prodigy, Dr. Zee. This character was played by two different actors (Robbie Rist for the pilot, James Patrick Stuart for the rest of the series), forcing a quick and sloppy retcon for the movie, vis-a-vis phoned-in Lorne Greene voice-overs, making them twin brothers, Dr, Zee and Dr.
Zen.

B+ for effort, Epic Fail for execution.
At the end of the day, the telemovies were just another money-grab opportunity to extract cash from the sponsors by Larson and Universal. They are largely ignored by the TOS fandom.
