Do Androids Dream of Electric Sheep is fine, but it's not Bladerunner so yeah it might be jarring. It's also not even close to his best work imo.

Some of my favorite Dick novels: The Three Stigmata of Palmer Eldritch and A Scanner Darkly. I think those are his two best imo. The Man in the High Castle is pretty good, but not at all indicative of his other work.

Now Wait for Last Year, and Flow My Tears, the Policeman Said, are also pretty good. I liked what I read of UBIK, but didn't finish it. I have a friend that swears by it though.

Some people swear by his latter stuff (e.g. VALIS), but I was never able to get into it. You can kind of see his mind starting to slip as you read his stuff (which leads to some incredibly mind bending shit in his early-mid works), and by the end, it's kind of nonsensical imo.

It's kind of tragic to read about his life at the time he was writing. The afterword of A Scanner Darkly goes into some detail, including listing the names of friends that "didn't make it" (usually due to drugs). Later, during the VALIS years, he was having full-own psychotic breaks and hallucinatory events where he thought he was Thomas from the Bible, living in ancient Rome or some shit. And his writing started to reflect all of this.

I've only read the first Hyperion book (and fucking loved it), but keep in mind, Dick wrote a different kind of sci-fi that was more about exploring consciousness, existence, the concept of self, psychedelic drugs, etc. as opposed writing space epics or whatever. Not to say that they don't sometimes take place in space, but just don't expect the kind of grand narratives you're gonna get with someone like Asimov. Completely different type of sci-fi.

That said, The Three Stigmata of Palmer Eldritch is his hidden gem imo. If you know, you know.
