For me, reading sci-fi in the 80s and 90s, my pantheon was (in no particular order):

Philip K. Dick (Man in the High Castle)

William Gibson (Neuromancer)

Neil Stephenson (Diamond Age)

Vernor Vinge (Across Realtime)

Greg Egan (Permutation City)

Robert Reed (Sister Alice)

John Varley (Eight Worlds series)

I'm sure every generation has its pantheon--I wonder what it is for Millennials and Gen Z.
