The last trip to Brasil I had problems with AirBnB - both incorrect listings (e.g. wrong location) and listings that weren't actually available.
I've used booking.com around the world and I can't recall any serious problem. When dealing with an issue, AirBnB error flow often sucks and booking is mostly fine.
When AirBnB works out great, you can find some real magic, but when it fails it really sucks.
I've found booking.com is usually more hotel-like and professional (e.g. contactable and reliable).
I still use both but I'm careful to choose depending on perceived risks.
