Ah, I was about to post "City and the Stars" before I read your post. Much better than the Rama and Odyssey books I thought at the time (decades ago). It's been a long time since I read any substantial amount of SF, but I remember fondly the works of A.E. van Vogt and Clifford Simak. Anything of theirs. I enjoyed Heinlein and Asimov, but I was 13 at the time, and they mostly didn't hold up to rereading when I encountered a few of them again years later. Not so the van Vogt, which had kept its punch.
And I have reread Stars My Destination about six or seven times. Oh, my, what a work of art that book is. Someone on the jacket blurb of one of the editions called it a "firecracker of a novel"; yes, but I would go further, it's more like a whole pack of firecrackers, an ever-mounting series of crescendos, of explosions of mind expanding ideas. Despite that it was written almost 60 years ago and the world has overtaken much of what was breathtakingly radical in both style and content at the time, and science has closed many doors which seemed legitimately open territory for hard sf; still, it holds up in the sheer poetry of the Bester style, the quirky, elliptical way he unwraps an idea, and contrives to have it detonate in your head. One after another after another.
If you are impressed with it now, imagine the impact it had in 1955. It was as revolutionary as if Hendrix had played Purple Haze in the '30s. ...well, OK, in the late '40s, say.
