Have a look at my previous replies. Although I believe there's more overlap in American English, as a British English speaker I don't see them as both expressing enjoyment.

For me, the sentence which expresses enjoyment is the version with like + Ving - while the other would be much more likely to be used in a situation where it means "I think it's a good idea". My usual example (and apologies if I'm repeating this from another thread, but as I said before, I can't find it) is:

I don't like going to the dentist, but I like to go every six months so that there's never any huge problems.

The first clause expresses my idea of how enjoyable it is, while the second says that I think it's a good idea.

Using an example with books like you did, I might say :

I like reading crime novels, but I know they're not really great literature, so every so often I like to read something more serious and intellectually challenging.

Again, the first part talks about what I enjoy, while the second says what i think it's a good idea to do.
