I very much prefer the first one. I felt that after the stratospheric success of that, her editor stopped editing and didn't do his/her job properly. Particularly as the books got bigger and bigger, a red line drawn through all the surplus paragraphs would have been a good idea!
I find this a lot with really successful authors. Their first novel is wonderful then subsequent ones are sloppily edited and much harder to read as a consequence. Proper editing would have resulted in much tighter novels, with really gripping action and better suspense, in the Harry Potter series.
