Islander,
My dos cents, after being a life long airgun lover, I've had them all break barrels, PCP, multi-pump, CO2, etc:
If you are heading into the woods, swamp, etc anywhere away from an area of resupply and you need to take all your stuff with you then a non-pneumatic rifle will be better. this is due to the fact that in time a PCP (pre charged pneumatic) will need "more air" and each subsequent shot gets weaker in FPS. ON the good side, a PCP is good for follow on shots and most can be shrouded to make them quieter. So for long periods hunting away from resupply a break barrel or multi pump is great. I'd go with a magnum break barrel.
If you are sitting on your back porch taking out pests, then a pneumatic would be best.
Keep in mind a PCP has a higher operating cost, due to the resupply of the air. A break barrel may be one shot but all you need is the gun and pellets, the maintenance is almost none.
Don't be too worried about the FPS and the velocities, most are under BEST conditions anyway. Caliber and shot placement are the important thing.
Lemma me know if you have any more questions, like I said before, I love this stuff.
