Canon SDK addons recap

Trying to find the right addon to control a Canon camera I couldn’t find a place that listed all of them, so here it goes. From oldest to the most recently updated:

ofxCanon by roxlu
CanonCameraWrapper by elliotwoods
ofxCanonEOS by wouterverweirder
ofxEdsdk by kylemcdonald

These are the 2 places to download the official libraries that you’ll need in order to use the addons:
http://usa.canon.com/cusa/consumer/standard-display/sdk-homepage#SDKQ3
http://www.didp.canon-europa.com/

I’ve been able to compile all the addons except for Kyle’s (I get a bunch of objective-c errors in Foundation classes ???), but I’d like to get an idea of the pros, cons and reasons to pick one over another, if anyone has experience with them.
