Humanity's Fire by Michael Cobley

Lightspeed Trilogy by Ken MacLeod

Revenger by Alastair Reynolds (the first book started off quite well, but the other two became a boring slog)

Rise of the Jain by Neal Asher. This one is just so egregiously bad, I don't know how I managed to finish. If I ever have to read another "erstwhile ship" I'll barf.

etc. etc.

Since I'm reading a lot of sci fi, I've ran out of top 1% or so of books an authors pretty quickly. Now I feel like I'm running out of middle-of-the-road authors, too.

Edit. I'll add that most sci fi is incapable of even writing characters that have more distinction than "she's a woman, he's a man". They all talk and behave the same.
