I use both sites quite a lot and at least 25% of the time Booking.com will say that they're taking payment at time of booking only for me to arrive at the hotel and find out that the payment has not been taken. For business travel this creates the annoying situation where I have to cover the cost of accommodation from my personal account and submit an expenses request. I have also had booking.com take the payment but there has been a break down in communication with the hotel and they have not received it or have not been informed and I've had to pay twice. Then spend time afterwards playing pass-the-buck as booking.com tells me it is the hotel who owes me the refund and the hotel telling me it is booking.com I've never had these payment woes with AirBnB.
