Matt,
Many people say you should use the same brand of tape as your camcorder. I don't think that's so important; besides... does Canon even make tape? But sticking to one brand is a very good idea. And choosing a brand that's been around for a while means they probably know what they're doing, and will be around for some time.
I chose TDK brand for 2 reasons:
1. I know TDK has been involved with magnetic recording for several decades.
2. I get a really good price on an 8-pack of TDK tapes at Costco, a discount store near me.
Just my 3 cents worth, :)
