evtricity, in my part of the world, CHAdeMO stations are plentiful, as are L2 stations. But you have to carry around your own (big, heavy, heat-generating) charger to use an L2 station, which is why they developed DC fast charging in the first place (to get that charger off the vehicle). If the CHAdeMO stations all worked, and probably even though they don't all work, I could get all around southern California using them without having to lug around my own L2 charger.
Supercharger looks great to me except for one thing: They're not located in the right places. They're (mostly) putting them BETWEEN large cities, with the idea that they're for people doing long cross-country trips in a vehicle with 200-mile+ range. Again, here in southern CA I'd probably be fine, but I can't venture far from here before they become too far apart to work for me. With L2 and/or CHAdeMO charging, I could refer to PlugShare and plan longer trips just because there are more of those stations around.
And, of course, nobody's got a supercharger solution available. I guess technically nobody's really got a CHAdeMO solution available either, which leaves us with L2 for now, further development of either CHAdeMo or supercharger for the future.
