I suppose that depends on the gun, and the co2 setup.
To me, when I think of HPA, I think its less flexible. ie not all fields carry it. Not availible for renegade, or backyard games. Tanks are heavier, and larger. Tanks require regulation (adding to weight, and complexity). HPA Tanks have a shorter lifespan, more likely to have a hydro failure, etc.
But everyones situation is different
