It certainly can be considered sloppy on some songs, but it's a good sloppy. Like Keef Richard's sloppy and loose playing. I'm not a big fan of surgical playing where every note is perfect--except a few like later Clapton work or EVH. But JP's sloppiness has such a cool swagger to it. John Frusciante's last couple albums with the RHCP's were VERY Page like, IMO.
Nowadays you get such clean and perfect notes it comes off as stale. I love hearing crunches and missed notes in songs, but those days are WAY past.
