Enterprise and Star Trek are my favorite Trek series.
And IMO, TNG sucked way more than ENT ever did. The characters were bland. The relationships were bland. Way too many of the stories sucked. Picard is a stiff. Troi is a bore. Crusher is shrill. Her brat is annoying. In fact, the only characters I found to be interesting were Data, Q, Ro Laren, Barclay and Guinan. Yup, for me only one of the main characters was worth watching.
That was even more true during the first few series. Later, it got better, but it's no coincidence that of the main cast, Data got more and more focus, because frankly he was the most interesting one. I agree that Barclay and Guinan were great characters as well. It always pisses me off when Wesley Crusher calls him Broccoli. I mean, seriously, kid? Who the hell are you to call people on their geekiness? It's not like you are the epitome of "coolness".

It was mean-spirited and totally uncalled for.
Inconsistencies aside - what I love about ENT are the characters, their interaction, their flaws, their conflicts. These people get launched into space with no clue as to where to go, what to do, how to behave. And when series 3 rolled along, they only had the responsibility of saving the entire human race dumped on their shoulders. Archer's psycho behaviour is excusable, and his character grows...he fights with his officers, but he listens to them. Janeway, i.e., doesn't have that excuse. Picard and his officers have no conflict.
While I like all the shows, I like them for different reasons. Sure, ENT has problems, and I see them, but I choose to ignore them and instead focus on what makes the show interesting to me; in this case, the characters.
Except for a few truly horrible episodes (coughcoughSpaceNaziscoughcough), the show is great and it had much potential that, in the end, could not be developed. Sadly.
