Here are some which, though perhaps not the best, haunt my memory through unique nostalgia.
Glory Season, David Brin. Ok, this is one of the best. A heartrending saga of epic scale.
Carve the Sky, Alexander Jablokov. Scifi feudalism.
All of an Instant, Richard Garfinkle.
Vita Nostra, Marina & Sergey Dyachenko. Though very different, it somehow reminds me of Roadside Picnic.
Spin, Robert Charles Wilson.
Schismatrix, Bruce Sterling.
Interstellar Pig, William Sleator.
The Carpet Makers, Andreas Eschbach
The Threshold series (Peter Clines) doesn't really belong in this list, but it is excellent and from what I gather, commonly overlooked by fans of Lovecraft.
I'd also throw in The Sparrow, Mary Doria Russel, if it wasn't so well known already.
In a different vein, if you seek good-old action-packed, kick-ass never-ending fun, pick anything by Larry Correia. Even if it appears fantasy, it might turn out to be scifi...
Interstellar Pig, was an unexpected addition there. I remembered that book immediately from hearing the title!
(On that note I remember a book I read at a similar time, some kids took off in a hollow asteroid, for reasons, and there was a home-made aiming system for their weapon(s) which involved using a cat. I've no idea what it was called or who wrote it. But I guess similar young-adult fiction.)
