Totally agree. TNG has the most accessibility if you're not a nerd Trekkie already, and thus it was my introduction to giving a shit about the Star Trek franchise - as such, my personal biases tell me it's probably my favorite and the best of the three. So far with Voyager, I get the feeling they wanted to leave behind some of the cheesiness of TNG but couldn't quite pull it off, maybe it's because the stories couldn't handle the content, like you said.
