Hate both. North Road FTW. They were widely referred to in the past as "tourist" bars.

I don't think they need to be very specific in design, but at least back-swept. Personally, I have North Roads and Albatross. I'd like to try Porteur, Bosco, Moustache, Promenade... I think at the correct height for each design, they could all work well.

Straight bars are only good for high-torque steering through rough terrain. Flipped "drop" bars are for tucking. Riding the hoods or bull bars requires a lower reach frame because the handlebars are essentially backwards. Riding the tops often trades steering torque and stability for a lower frontal area. If they're wide enough, the position is no different than straight bars.
