Quieter edge or amenity-rich neighborhood for long-term value?

I’m comparing two candidate areas for a custom build, and the main question is how much weight to give future development.

Area A is quieter and less served today. Schools, shopping, parks, and medical services require a longer drive, but peak-hour traffic is lighter. There are proposed residential and commercial projects nearby, though their timing and final scope aren’t certain.

Area B is busier but already has established schools, retail, parks, and essential services within a shorter drive. Commute traffic and road noise are noticeably heavier, and additional development could increase both. On the other hand, the existing amenities may support stronger resale appeal if future projects are delayed.

Before choosing, I’d review approved versus merely proposed developments, road-improvement plans, peak-hour travel times, school capacity, and whether new services are actually funded. For those who’ve compared similar locations, did established amenities outweigh traffic and noise concerns, or did planned growth make the quieter area the better long-term fit?
