I like Philip Dick a lot, mostly for his ideas. I also like his storytelling, it makes me laugh without trying. His characters and dialogues can be very funny and snappy and I can't put my finger on it.
I do think his short storries are generally much better than novels. My favorite compilation of short stories is "The Days of Perky Pat". It may be known under a different name, for example in my country "My, zdobywcy" because the pun can't be translated.

Some of his short stories are fun because they're so retro. For example analog robots, no computers, no internet. It's like an alternate history and I can enjoy that !
Other short stories are still up to date, you can even say prescient (The Mold of Yancy). I particularly liked Explorers We. I like The Minority Report (inspired the movie, not the other way around). What The Dead Men Say is an abbreviated Ubik (although Ubik is one of his novels I like).
As for his novels, I disliked Man in the High Castle - I don't understand what the fuss is about. But I hearthily recommend
A Scanner Darkly. It reads very well despite having few sci-fi elements (which are crucial to the plot, though). It has elements of autobiography and is in parts creepy/tragic/funny/scary. It reminds me of the movie Requiem For A Dream, except that I don't like the movie that much.
