Untethered performance, battery, and ergonomics:
AMD laptops may further limit power draw to conserve battery when unplugged. Also, some laptops draw air from the bottom, making it impossible to use in bed. In essence, if you choose AMD, then you're limited to sitting upright before the desk. MacBooks don't have this limitation. When you want to code, you can just flip it open and start, and its battery lasts ages.
