Same print quality and speed: the only real difference is build volume
Quick answer: Get the A1 ($299) unless you are sure a 180mm build volume covers everything you print; the $90 street difference buys meaningful extra capacity. Get the A1 Mini ($209) only if you print small objects and want the cheapest Bambu entry point.

The A1 and A1 Mini share the same print head, the same calibration system, the same nozzle design, and the same AMS Lite compatibility. Print quality and speed are identical. The main functional difference is the build plate size: 256 mm cube on the A1 vs 180 mm cube on the A1 Mini (and the A1 bed heats to 100°C, the Mini's to 80°C).
The Mini's cube holds about a third of the A1's volume (5.8 L vs 16.8 L). That matters a lot for certain projects and not at all for others.

If you're genuinely on the fence, get the A1. You'll never regret having more build volume. Plenty of people have regretted not having enough, and upgraded from the Mini to the A1 within a year of buying.
Both printers include: full auto-calibration, magnetic flexible build plate, filament runout sensor, power loss recovery, Wi-Fi + Bambu Studio / Handy integration, and AMS Lite compatibility for 4-color printing, or up to four AMS units via the A Series AMS Hub.
