Vonnegut wrote in confuso-prose many a time, same as Dick. I liked some of the Vonnegut I read, but I never felt the need or desire to read more.
Really what we're describing here is personal taste, so there's no real direction to go in. I do enjoy the occasional non-traditional novel for a change of pace, but I have rarely enjoyed the truly odd or ethereal. Dune I couldn't stand, I tried a couple of other Herbert books and they just defeated me. I'm a big Heinlein fan, if that explains anything.
I liked the first Covenent series because it was different for epic fantasy to have the main character be an unrelenting a$$hole, but 3 books of that guy was enough - I hated the second trilogy. I haven't honestly read or enjoyed much fantasy at all over the last ten years or so, unless you're willing to grant that Brust's Jhereg stuff is fantasy. Which it kinda is.
