A lot of it has to do with feedback and handling. Near wedges tend to offer a lot less feedback than full hollow ground razors - you get less vibration and ping through the meatier blades. On the other hand many (including me) feel that wedgier razors offer a smoother experience - they tend to treat my skin better than the lighter, full hollow ground blades. It may be a question of the amount of blade deformation under pressure. I like the handling of the extra weight too - the razor seems easier to control by just letting the weight and momentum do the work.
All razors are ground to some extent - a true wedge would be nearly impossible to hone. You often see the wedges in the form of big 8/8 cleavers - people like the impressive look. But I think there is a sweet spot in a 6/8, 1/8 hollow blade. My W&B chopper is a great razor, very smooth and a lot of fun to shave with.
But it is bested by the slightly smaller Greaves which takes a ridiculous edge and is just about perfect with regards to handling - for me at least.
