Better in what way? They're products of different eras. It's like comparing Man From UNCLE with 24 -- there are superficial similarities, but they're really not the same kind of thing at all.
TNG made TV history in a lot of ways. It was the first successful big budget hour long drama series in syndication. The last few seasons represent the peak of Star Trek's mass popularity -- it was never more popular than it was for the last few seasons. Not that popular = good, necessarily, but it was an undeniably significant phenomenon. It revitalized the Star Trek franchise. It created some iconic characters. And it had some really great episodes.
Ron Moore's Galactica could have been the best SF TV series ever, if they'd actually planned it out and thought things through more carefully. No SF TV has ever had the kind of critical acclaim that series had, but that never translated to ratings. As I understand it, more people watched Enterprise than watched Galactica. Again, popularity doesn't imply quality. Few have taken the kinds of dramatic and storytelling risks that show took. But it is less than the sum of its parts, because it was all supposed to be building towards revelations that really didn't make a shitload of sense because Moore et al were making too much of it up as they went along.
So... they're both really important. Anyone who wants to pretend to have any kind of informed opinion about SF TV needs to be familiar with both. Is one better than the other? Well, one always had me wondering what the hell they were going to pull next, and the other had a lot of predictable standalone episodes, so Galactica gets the edge there. But there aren't many individual Galactica episodes I'm going to want to rewatch because they don't often stand on their own. TNG episodes are more rewatchable because you can get a complete experience from one or two episodes. TNG gets the edge there. Plus, TNG quickly became its own thing. Galactica could never shake off the whole Ron Moore this-ain't-Star-Trek thing; they did too many dumb things for no apparent reason beyond "ha! you won't see THIS in Star Trek!"
So... I like 'em both. For different reasons.
