Well Continuum was the better of the two but I'm just sick of time travel. But the audio diary from Ben Browder was a nice touch (what he did for the 10 years before Ba'al activated the gate).
I'm working my way through the 10 seasons of SG-1 and also have Atlantis which I haven't watched yet. Frankly I prefer Star Trek, a lot of Trek storylines seem to be recycled on this show, but it's still entertaining. I have reviews of the first two seasons on my blog.
Imho, Stargate Universe was a very poor attempt to make the Stargate-verse look like the new BSG - and they failed miserably. I was so bored by Universe that I gave up on the show after 5 episodes.
SG-1 and Atlantis were so much better and more entertaining...
