I've been wearing Sidi Giau's (now discontinued) in Mega width for six years. They have been pretty good, although I've replaced the insoles multiple times as they are thin as cardboard. Rarely any hotspots or problems at all. They never feel too tight.
I'm considering springing for some Dominators.
3E-4E foot here. For what it's worth, I have a pair of Sidi Giau Megas, too, in a size 42. Not too long ago, I ordered the same size in a Sidi Five Mega from the UK hoping that they'd fit the same. And they did. So at least in my experience, Sidi shoes fit pretty consistently even going from fairly low end to the fairly high end.
My dad has the Dominator Megas and loves them, too.
