I expect higher end tools or equipment of any type to perform better than midrange or lower end in most circumstances.
Aside from paying for a name, when you spend more on a given tool you are usually buying higher quality materials, machined to tighter tolerances, better engineering, quality control and so on.
With this usually comes better performance and often longevity.
There are always exceptions of course.
I do not own any high end airguns, my most expensive being in the 5 to 6 hundred dollar range, both of those are PCPs.
I do not expect my less expensive guns to make the same caliber shots as my more expensive ones but some do, and some even better.
I find that impressive and when I have a very successful hunting or pesting trip as I did yesterday with my 177 Kral NP-03, pesting pigeons etc at a steer farm permission, I find that to be very satisfying.
My buddy who shoots a Taipan Vet. in 25 was impressed at how successful I was with that gun, most kills at 30 -60 yds, in somewhat windy conditions. Most of his shots were 50 - 80 yds. I am not a better shot than he is, he is probably a little better than me or maybe more than a little, but he was not doing as well as he usually does.
I probably made twice the kills he did, yesterday anyway.
We were both impressed with how well the NP-03 performed.
I was thrilled to have the successful hunt that I did with a less expensive medium powered 177.
I think it is very subjective, I expect the same gun, you name it, to make more kills at a given range in 25 cal than in 177. Sometimes though the 177 may do just as well and that is more of a challenge in my mind and more impressive. This kind of performance likely varies though from one day to the next though.
