I use it (Skype) regularly to talk to a friend of mine on a PC across the ocean and it works great. We can even send files to each other (we both take tons of photos).
I've used quite a few and Skype seems to be the best for video chat at least. My recommendation is just try them out and see what you like. They all do just about the same thing, so it really comes down to what you are comfortable using.
The trouble I have with Skype is that they update the PC version far more often leaving Mac users in the dark. Macs just recently received video chat and that's driven me away from Skype.
Unfortunately my Airport Express hates my Macbook Core 2 Duo so I wouldn't really say anything about Video Quality in iChat/AIM until I receive a similar update for my Express as the one they gave the Airport earlier this month.

Never used AIM so I can't compare.
Good luck!
