As long as it is not flat bars your are good

I use both, upright bars on my "hop on and ride bike" that i use for errands, casual ride, backup commute bike and drop bars on my main bike

I find, especially with brifters (and i have a downtube friction dropbar bike also) it is faster and more efficient for my commute and longer rides

on the other my upgright bike is fun for just casual riding around.

so it does not have to be one or the other...unless you want it to be
