I voted for Farscape. Though you should check Blake's 7 sometime, if you haven't seen it, so many great characters: Avon, Vila, Servalan, Travis and Orac at the top of the heap, and many others that make up a strong second tier. The SFX are rickety, but, the characters are great, and the scheming is awesome. And in some ways, Farscape seems to be very inspired by Blake's 7.
Though Atlantis would be really cool too (Atlantis would give me a chance to get Clone Wars in before my own SGU Rewatch, since I only have 10 more Doctor Who stories for my Classic Who rewatch)
