That is 100% rider preference.
My wrists are Carpel Tunnel and the drop bars were not working for me. There are times where I really wish I had them when fighting a head wind or the rare occasions I see 30mph.
In general slow speed stuff in traffic I like the upright position of the 2 inch risers I have. I can see over and through most cars and SUV's to see the car on the other side and what they are up to before I get in front of them at intersections and side drives.
