Didn't DS-9 come before Babylon 5? Personally, I liked that series the best. It was dark, there was the war with the Dominion. Lots more Klingons, and it got really good when Defiant and Worf joined the cast. J.Dax was totally boneable the way only Ensign Roe was hot on Next Gen.
As for Kirk v Picard- I think you have to consider that the two series were very different. As a series, I think the quality on the Next Gen was better.
But overall Kirk is way the dude compared to Picard. Picard almost never got laid. Seriously, How many times did Picard get some good alien punani. Which was really what the show was all about. Kirk was getting nukki all the time. I mean, the whole show was about him getting alien action. True, Shatner is a crap actor compared to Stewart, but Shatner is a better and cooler captain of a space ship. In TNG, Picard is captain of Star Fleet's flag ship, so its all prestige and shit. But Kirk is just badass and he's really going into new space.
So yes, the original series kicks ass on the NG. For instance, Geordi vs. Scotty- no contest. Scotty kicks Geordi's ass. Geordi is a geek who masturabates in the holodeck. Scotty ended up shagging Uhura- who you know has got to be hot in the sack.
Wesley Crusher- Jesus fucking Christ!
Ok Riker- total loss.
Sulu and Chekov were so much better him.
I liked Worf- and no shit, the show got better when you had Worf Klingon episodes.
Data vs Spock- please. Spock was way cool. Data was just dopey. He's an indestructable android who is like super brilliant. vs Spock who is all about the logic.
Bev Crusher vs Bones? No contest.
The problem with The Next Gen- was that the cast was a geek fest. The original show the characters seemed more real.
As for Voyager- ah... it got ok. I couldn't get into Janeway and the later series got a bit boring when I realized that all I really wanted was more of Seven of Nine in tight clothing. There were some good Borg episodes but the first couple of years was pretty thin. What was with that fucking dude who looked like a skunk anyway? That was a show that was totally done over and was still pretty weak. Seriously, Seven of Nine carried that show.
As for Enterprise- I didn't watch it all, mostly because I was married and my wife didn't like the fact that I was watching T'Pol, but hey Jolene Blalock was the hotest of the Star Trek babes.
I thought Trip was probably gay, and Archer was ok, but a bit stiff. The supporting cast didn't get enough attention.
