Another theory is that open comb razors work better for thick growths, as the hairs can slip around the comb and get mowed down by the blade, as opposed to being squashed down by the safety bar (which could make it hard to deal with several day's growth).
I think this is hogwash (as far as intent in the designs).
My theory (completely without proof) is that OC DE razors were made first as it was easier to machine them from the metal blocks (as early DE razors were made). When they started using stamped metal for the base plates, it became easier to make safety bar heads (these were also sturdier). Of course, the companies kept both types going with some spin (just as Gillette does today with the number of blades).
OC razors do work better with several days growth, due to reasons mentioned above, but I think that was something that was noticed later and used as a marketing line.

Having said that, when I use OC razors, I don't feel the teeth at all. Different people have different sensitivities, but I'd say that either an adjustment in blade angle or pressure should take care of that issue.
If you're going to go with OC razors, try a fat handled long comb Gillette NEW. Those generally work for the most people.
