I think VOYAGER was the most compelling of the series, because they were underdogs & not necessarily the best of Starfleet. The need to get home and all alone in often unfriendly surroundings, is also compelling.
Here's a question: Why is one of the biggest criticisms from Trekkies- "not enough conflict between Maquis and Starfleet people"?
What kind of conflict exactly did you want? Are all these people suppose to be itching to brawl, or always ready for a shouting match? Are the Maquis a bunch of Live Wires, that upset about Starfleet, Ready to go ya? That gets old fast, and is irrational.
(Here's the problem: DS9 already proved that audience generally don't dig ongoing fictionalized hurt feelings: I.E.- Bajorans.)
It's the "bigger picture"- they're all in the same boat & need each other to get home. That's more compelling than a Maquis with a chip on his shoulder with, say, Tuvok over God knows why.
I think the producers of VOYAGER generally made good choices for the ongoing health of the series. Sure, some choices were headscratchers- like Chakotay getting with Seven instead of Janeway.
