I have the Oceanic Shadow and it is really nice. I originally got one as a backup to keep in my drysuit pocket, but liked it a lot so got another one to replace my main mask that was starting to fall apart.
I also took a look at the Scubapro frameless, but liked the Oceanic better. I think the Oceanic has lower volume, although I'm not completely sure. The Mini Shadow has even lower volume, but it probably also has less vertical field of view.
As for fogging, my first one had the fogging problem, but when I got the other one, I scrubbed it real good with toothpaste/toothbrush and it didn't fog. I guess I needed to use the toothbrush on it as well, not just the toothpaste, as I did with the first one.
