Hmm... Thinking about it, I guess SG-1 is a bit more action oriented. But I think that's because it went on much longer than Atlantis. If Atlantis had less action, it was because it tried and failed - not because it was intending to be more "talky". One of the defining moments of Atlantis is a gigantic engagement in space. It was so important they changed the show's intro to include it.
Rest assured, SG-1 has a lot of great dialog and thought-provoking stories, too. I guess you got unlucky and saw all the "YEEHAW, MURIKA!" episodes. XD
One episode in particular is really rough because it focuses on the emotional aftermath of a single action scene.
The reason I called SG-1 "well-rounded" is because it's a terrific balance between action and character. Atlantis does the same with less on-location filming, and a smaller budget. It's really hard to pick one over the other because you should treat both as a complete set.
Original Galactica: Somehow makes TOS feel mature and grounded.
Reimagined Galactica: The original grimdark reboot. It's one of the few works that did "grimdark reboot" well because at the time "it had the virtue of having never been tried."
This is what Ronald D. Moore did in response to being replaced on Star Trek Voyager for trying to make it the exact same kind of show but was told to make it light-hearted and episodic like TOS or walk. So he walked.
Fuck you, Rick Berman.
