True, although you might be surprised, Tor isn't the trickle of bandwidth it was in the past. But the real goal here is not speed, but privacy. A VPN's "no log policy" is all good and well, but there is always the risk, that in some future crack down on filesharing via VPN those businesses will just be run by law enforcement for a while, logging whatever they need to build a massive case against a bunch of people. It might be a small risk, but Coinado is torrenting for the paranoid. ;-)
Considering that it has already been revealed that the NSA is actively looking into Tor (and they have some of their own exit nodes IIRC) - I'd be more inclined to think a seedbox created from scratch on a VPS in a grey jurisdiction would be the best. Next best would be in countries with little need to comply with DCMA (ie. few treaties) such as eastern Europe.
Secondly, it depends on where the VPN's are actually located - can't build a case on evidence that hasn't been legally obtained. You'd need a warrant first to get the logs and no unauthorized surveillance would stand a chance in court.
