I wouldn't use anything but drop bars. ...
My definition of "commuter bike" begins with the words, "drop bar road frame".
Same here.
I ride a lot with my hands on the middle/top of the bar when I'm just cruising or need to see better in traffic. And I probably ride at least 1/3 of the time in the drops, I'm lucky to be still reasonably flexible.
My beater/MTB bike has a riser bar, my other bikes all have drop bars.
