I don’t ride competitively. But, FWIW, I have one very aero bike. The southern New England area that I live in is always windy (great for sailing). It’s noticeably easier riding that bike in a headwind. But riding it in a cross-wind can sometimes be perilous, and not fun. For that reason, I’d prefer lightweight over aero. I so guess you might want to consider weather conditions where you ride.
