I have read both and I also like PAIP better. I find PCL good only for somebody that don't have much programming experience. I believe that somebody that is a seasoned programmer and that wants to gets some understanding of CL will appreciate PAIP better. This is because PAIP begins with an introduction of the language that just touches all the basic stuff upfront very clearly and only afterwards starts to build on examples. So if one wants only to get an introduction to CL he can just read the first chapters and forget the rest. PCL does the opposite introducing just a few features at a time and providing a lot of examples side by side. This might force the reader to pay attention to stuff he is not really interested in.

P.S: I found the examples/practice part quite boring in both cases but for sure PAIP is more interesting as there is a chance to learn something new/unusual.
