Both holds their own advantages and disadvantages.
For example, Response time in Air Brake is very less compared to Hydraulic brakes, but the system requires a compressor for pressurised air, reservoirs to store them, which indeed increases the no. of components and weight. IMO
air brakes are highly responsive, efficient & safer than hydraulic brakes.
No clear idea bout Power Brakes. I have seen such stickers in Ambassador Cars, AFAIK
they are with some after market bigger brake boosters (vacuum assisted)
