Neither. The GPLv3 was motivated by practical concerns (tivoization, etc...) and it solves those to the satisfaction of the FSF. GNU software uses it, though Linux and much of the rest of the ecosystem does not. I don't think it's failed.
But it doesn't read like GPLv2 did. The v3 document is longer, with more definitions and more "legalese". It seems like they wanted to "polish it up" for the legal community, but in doing so I think they lost a lot of the beauty of the original.
