What caliber of airgun is best?
The is no definite answer here. A lot has to do with personal preference and what you plan to use the airgun for; hunting, pest control, plinking or formal target shooting. Generally, most target shooters and plinkers opt for the .177 caliber. A lot of shooters select .20 or .22 for pest control and hunting. Some even use some of the bigger calibers like .25 and 9mm that are now available. However .177 can be used for hunting and pest control as well. Generally speaking, larger calibers retain downrange energy better so they impart more energy onto the target.
