Vanguard is darker even than DS9, so not everyone’s taste.
What it does have is not only Starfleet on-station but also 4 ships that are based there from a scout explorer to a Constitution class. It’s a lot of characters. Plus Tholians and Klingons. The mystery takes a bit to come together but it’s excellent.
The Enterprise and her crew show up occasionally but aren’t the primary characters. There is one Vanguard novel recently add that is Enterprise-focused and is one of the best books since Destiny.
I found the Voyager books when they return to the Alpha Quadrant very frustrating and disappointing. I DNFd the second one.
It seems like the tie-in auto Christie Golden was required (by the IP holder) to break the Voyager crew up and make them experience a great deal of unhappiness.
In the main series of post Voyager 24th century relaunch timeline novels post Nemesis, longstanding author Peter David was obliged to kill Katherine Janeway off in one of the crossover events!
That said, I did really enjoy Kirsten Beyer’s Full Circle Voyager novels. Beyer was eventually given permission to get the Voyager crew back together for a new exploratory mission to the Delta Quadrant with a group of slipstream ships.
