Wide drops are better if you have to hang a bag on them, that's simply a fact. Some normal un-flared bars are literally unusable (you can't brake) with certain bags.
Otherwise, different people are going to find different things comfortable, and some people seem to care about being aero and some people don't, so ride whatever you like surely
In my experience flat bar hydraulic brakes almost always direct the hoses into the "maximal crushing" zone when used with a bag, resulting in horrible 90° bends at the lever end and turning the hoses into a load-bearing structural element
