I have the opposite view to the OP. I have a shelf stacked with the books from the 90s, and pretty much stopped buying after 2000 (the Millennium trilogy was the turning point - I found that utterly awful).
I've picked up quite a few of the recent ones from my library and some have been good, but most have been utterly forgettable and a few have been unbearable (just last month I returned one unfinished, which I've never done before).
None of the relaunches other than Enterprise captured my attention, and even then I wouldn't rate them among my favourite Trek books.
Each to their own, but I'd take the "old Treklit" any day.
Kim: I'm detecting some weird technobabble.
Janeway: A possibly dangerous anomaly that we know nothing about?
Kim: Yeah. I suppose we should steer clear.
Janeway: Ha! Good one, Ensign. Take us in, Mr. Paris.
