The biggest hurdle with cantis in general is getting the hang of adjusting them. Once you can do that, any of them that allow toe-in to be adjusted are good enough for commuting.
Its funny that catis are supposed to be some of the weakest brakes out there, because in my experience, they seem more solid and strong than sidepull or v's. I've never actually owned a bike with anything aside from side or centerpull though... I'm just judging from bikes I've built and worked on. I totally can't stand cheap sidepulls... anything lower quality than 105 is useless in my opinion... and I just don't like the feel of v's... they seem spongy to me. I have really been surprised though how strong center pull and cantilever brakes seem to be on some bikes.
