I like the Ritchey Biomax.

Broadly, there seem to be two types of ergo bars. The ones with the "bump". like the Biomax, and the ones with straight sections. I find the ones with the bump comfortable, with a shallow drop. The other type doesn't seem to have a good place for my hand. Don't judge all ergo bars just because you had one you didn't like, there are plenty of differences between models.

If you don't want ergo bars, there are plenty of normal ones still around. Ritchey makes an expensive one. Profile makes a $30 model which is nice. And there is always Nitto.
