I have quite a few PCPs, and quite a few break barrels and CO2 guns, but If I could only keep one it would be my Prod. Hands down.
It is deadly accurate at backyard ranges (up to 50yds). I have a DonnyFl Ronin on mine and it so quiet I can shoot it out my dining room window without my wife even hearing the shot from the next room, and there are no doors separating the rooms. It is reliable and simple to work on. Handful of o-rings. Maybe 6? I have a compressor but I don't bother with it for the PRod because it only takes 30 strokes on a hand pump to go from 1800-3000psi. Great trigger. Light weight. Not pellet picky. Perfect squirrel or pesting carbine with a stock. I have a simple aluminum tube stock on mine and have never actually shot it as a pistol. That Prod has taken almost 1,000 grey squirrels and hundreds of rats in the last 10 years. Without question my favorite, most used, most practical gun.
Get the PRod, a carbine stock, Bug Buster scope, you have a perfect little carbine. Accurate with all of the quality hunting rounds: JSB Hades, Polymags, Crow Magnums, JSB Ultra Shocks, FT trophies, even Predator GTOs.
