Cool is cool.
The thing I like about the Freez-it stuff is that it comes out as a liquid if you hold the can just so and spray with the right velocity. This is important (or rather, nice) because it lets you direct the coolness right to the bits you are interest in.
For example, if you want Thing A cool, you drizzle some liquid out of the Freez-it (or equiv) and onto Thing A. Thing A causes the liquid to boil, which sucks heat out of Thing A like mad (it is a phase transition thing -- gobs of energy are required to go from liquid to gas).
I have no experience with CO2, but I don't THINK it comes out as a liquid but again, cool is cool. Expanding CO2 takes energy (though I don't know how it compares to the liquid->gas transition of Freez-it) and that energy comes from the surrounding environment. If you can control the CO2 such that you can get the heat out of a particular part or group of parts, it should work fine.
