Poseability and accessories. Right from the get-go Joes had much better articulation than other 3.75" figures (like Star Wars...) and that's only improved, for the most part. Plus the quality and range of accessories & playsets allows for a huge variety of scenes.

Also I think there's the real-world aspect; because GI Joe takes place in "our" world, not outer space or some fantasy realm, it's easy to find or create settings that look appropriate for them. They're essentially regular humans too, in general, so special effects can be helpful but aren't essential for an effective dio. I collect Marvel figures too (Legends and Universe) and while I've got a few shots of them in my Flickr account I'm much less inclined to take dio-shots of them than I am Joes, because to portray the Marvel characters in an exciting/worthwhile way would usually mean replicating some kind of superhuman ability (flight, energy blasts, etc).
