Is Firewire a better way to capture DV than USB 2.0?

Realistically, firewire is the ONLY way to capture video.
Never, ever, ever, ever, ever use USB.

The other points are it doesn't carry the audio signal like Firewire does and most modern video editing packages are set up only to work with Firewire. I think USB2 is actually faster than Firewire in terms of data transfer, I think one runs at a quoted 480MB/s and the other runs at 400MB/s, correct me if I'm wrong.

Firewire runs at 400mbps continuous. USB2 "upto" 480mbps if it wants, when it wants and that is generally only when it is connected to a printer or something, and who needs 480mbps for that.

Yes, USB 2 is faster on paper, but in reality it's not capable of continuous, uninterrupted data streams, hence the dropped frames and/or chopped audio.
FIrewire is more than fast enough for DV and it's entire design was intended for long uninterrupted large data file transfers. Originally it was intended for interfacing with high speed external hard drives. The video industry latched onto it when digtal editing started to replace the old analog linear methods..

I am afraid I strongly disagree with the others 
USB 2.0 is perfectly adequate for capturing video. In fact Avid's Liquid Pro captures High Definition Video over USB 2.0. While you can bang on about 480 versus 400 and burst and sustained data transfer rates, you should work out what the bit rate is for the data you are actually transferring. HD 1080i requires a sustainable bit rate of around 25 Mbps! So you tell me which of those two formats is better for transferring a data rate of 25 Mbps?
The excellent Panasonic PV-GS400 for example allows the transfer of your video via it's onboard USB 2.0 port.
If this was a question about HDD data transfer rates then this would be a completely different discussion (in which IEEE 1394 would of course win out).

Actually I will add one other comment. While the transfer rates are perfectly adequate, you should make sure your software will support the recognition and control of your camcorder through a USB port. That can definitely be an issue. I think presently only Avid Liquid supports this, although the new Adobe Premiere Pro 2.0 may (you'd have to check).
