I've tried ergo bends a couple times and never quite liked them. The flattened part of the drop may fit into the hand a little better, but it puts the lever slightly further away, all else being equal.

So my favorite classic-style handlebar is the Nitto B115. It has a sharper bend at the rear corners, giving a little more straight length on the tops and ramps for your hands. (That's the thing I couldn't stand about the GB Randos that Darth Lefty loves, they're narrow and curved every which way on top, so I couldn't find a good place to put my hands except the drops!) The B115 also has an 8-10 degree flare to the drops, making them more comfortable in a couple of positions, to Stewart's point.
