I don't like keyboards that need charging so I've been using the Logitech K750 for Mac (white) keyboard. It's solar powered and daily exposure to indoor lighting will keep it going.

The keys are quiet but feel jiggly at first compared to how little MacBook keys move but you don't notice after a few minutes. The only problem I've had is trying to use it with a desk with an under table keyboard drawer which didn't keep it charged.
