1. You need to trust your DNS provider. You may not trust Unblock-Us as much as your ISP (or you may trust them more, depending on your ISP I suppose).
2. It costs $5/month. Very inexpensive, but the alternatives are mostly free. They just don't do the proxy thing.
3. Because the Unblock-US DNS servers aren't local, DNS lookups take a little longer than your ISP's DNS servers. At least, that is the case for the Shaw DNS servers.
The Unblock-US DNS servers seem to take around ~60ms to resolve a name, whereas Shaw's take about 20ms. When you visit a website there are usually a lot of names that get resolved, so the performance impact of this is worse than just 40ms.
The benefit is that you get no-hassle access to US content on all your devices. I recommend setting it up on your router rather than doing it per-device, and only for streaming devices. That way, when you're on your Mac or your iPad and you click a link that someone posted on Facebook to the latest Colbert Report episode on the Comedy Central website, you will see the video, and not get blocked because you're in Canada.
The only real reason not to set it up (IMHO) is because of the trust issue, but it's not like I trust Shaw, Google, or even Open DNS more than Unblock-US.
