I can't tell about HP but a few days ago, I got Pulsar .25 from AOA. It's just sick... I had Hammerly, couple Evanix airguns, couple Hatsans this one it's like switching from Ford Taurus, not even to Mercedes, but directly to Bentley.
I guess, if you planning to use for long distance shots, HP makes sense, for me, it's not necessary, most of my shots are close to a house 10-20 yards max, shorter rifle size is better.
Cycles through the shots absolutely effortlessly, trigger is extremely smooth, no jumps, just positive click, no recoil, endless shot count and on top of everything it's dead quiet. I can't even compare it to my Paslode nailgun, I would say it's like battery operated nailgun, when you can hear only how nail sinks into the wood. Same here, you only can hear how pellets sink into the target.
Accuracy is beyond my expectations. Few times I had to go and check my target, I would shot 3-4 shots from 25 yards and it's still only one hole on the target, I'm not that lousy to miss a target completely, had to go to the target and dig that hole with my knife, all pellets stacked in one hole, I'm not used to that kind of accuracy.
Plus some small, but pleasant details - you always know how many shots you have left (digital display has shot count) magazine has holes, you can see pellets inside, after last pellet in the magazine - rifle vibrates to let you know it's empty. Low on air - vibrates again.
