Fair play, so your opinion is not biased then
I don't have a best, each have their benefits.
I have a S10 carbine for general mooching and ratting, fairly lightweight but the short barrel means it can be swung around easy or convenient for shooting out the motor.
Rapid MK1 for general use, The dogs balls.
A HW35 for kicking about the motor, good close range rifle, ideal for pigeons in loading bays or barns.
I regrettably sold my HW98, which in my opinion was the best springer I have owned (and I have had a couple )
Im on the fence
