I just finished reading the Hugo winners.

2. So many wonderful old classics, books I read back in the 60s.

Either that says these books are enduring masterpieces of this genre that have withstood the test of time and competition, or the competition is lacking and there are no new storylines that are strong enough to knock those old treasured tomes off the shelf.

On the other hand, in this age of digital publishing and ebooks where anyone can earn the right to be called a writer there are thousands of new authors with small, but loyal fans. It's becoming a niche market and perhaps the competition is so crowded and varied that it's virtually impossible that any single book will ever again rise to the top of the heap to replace one of the established classic titles.

In no particular order, off the top of my head, my list starts with;
C. J. Cherryh's Foreigner series
The Chronicles of Elantra series by Michelle Sagara
Alexis Carew series by J.A. Sutherland
The Golden Age of the Solar Clipper, Nathan Lowell
The Expanse series from James S. A. Corey
