I think there's a reason the 6.5x55 Swede is so often coined as "the .30-06 of Europe". Sure, on paper it might line up a bit closer to somewhere between a .243win and a .270win, or parallel to the 6.5 Creedmore (although the Swede handles bigger bullets a bit better), but the moral of the story is that it's versatile and effective.
I have had two rifles in the Swede, a Mauser that I bought on a whim for $80 when I was still in high school (gunshow loophole!), then a Ruger M-77 that I wish I had kept. Both were fantastic deer rifles, and buckled antelope like a house of cards. A little heavy on coyotes unless you're measuring in football fields (or unless you're not fur hunting).
The Mauser was actually more accurate than the Ruger for most loads, but both were fantastic shooters, light recoil and surprisingly good killing performance on heavy bodied KS whitetails.
