Neal Stephenson’s “Cryptonomicon”@1999, Avon Books and Iain M. Bank’s “The Algebraist”@2004, Orbit. Both of these excel in character development, compelling narrative, adventure, and world building. Over the decades I believe I’ve read each 4 times.
Honorable mention: Ray Bradbury’s “Something Wicked This Way Comes”@1962 at least 4 times but pre-millennial. Also, a much shorter read.
