This handlebar is perfection incarnate. Here's why:
The shape: grab a pipe or broom in your hand and hold it in front of you. Hold it at various angles... you'll find that at a perpendicular horizontal angle like a typical flat bar puts pressure on the flesh between your thumb and index finger. The most comfortable angle? 45 degrees. And this bar has it.
Combine the handlebar with a set of grips like the Ergon GCs now you can comfortably put some weight on your handlebars because your weight is resting broadly on your palms like a pushup (albeit much less) rather than just where your palm meets your wrist. Now tucking down to get more aerodynamic isn't painful - and you still have immediate access to the brakes shifters and whatever else is on your bars. You won't get that on a drop bar. If you're riding in a city you need constant access to the brakes for safety.
When you can rest much of the weight of your torso on palms it makes it much easier to really hammer the pedals with your legs. Speaking of push-ups when I'd tuck down it would feel nearly like a pushup position with your hands rotated outwards slightly to take pressure off your wrist.
But if you don't want to duck down you don't have to this handlebar is perfectly comfortable while sitting relatively upright. It won't give you the range of 'sitting height' that a drop bar would but a) that much range isn't necessary and b) the drop bar doesn't give you access to shifters and brakes when your hands are on the top-middle of the bars.
And now since your ergonomics are perfected you won't need 'multiple hand positions' like so many people advocate (dumb dumb dumb for urban riding). Even if you're touring you're usually stopping enough that one position if set up well should suffice.
There's also the width: It's relatively narrow. That makes splitting between cars and through crappy tiny bike lanes easier. You could probably even chop a centimeter or two off each side if you want. I didn't because I have it on an ebike with extra controls so I needed all the space. But something worth considering.
The bar is from Velo Orange but it's similar to an older bar from another maker the Nitto Jitensha.;
