Deer ain't hard to kill. IMO a 243 kills them just as dead as anything bigger. Even a 22 centerfire will kill deer, but you have to make better choices as to the bullet, shot placement and the range you shoot.
Sometimes a deer, or any big game animal just doesn't want to die regardless of what you hit them with. They are dead, but sometimes it takes a little time for them to lie down. I had a grizzled old buck that I put a 165 gr bullet fired from a 30-06 that took out both lungs and left a 2" exit hole. He still managed to run over 100 yards. I've had them fall in their tracks from a 223. Just because one runs a long way doesn't mean you need a bigger gun or better bullet. Sometimes it just happens.
As long as I shot it equally well that would seal the deal for me. The 270 will have less recoil from equal weight rifles and is more than adequate. Which means most people will probably shoot it more accurately.
I like the 300 WSM cartridge. With the best loads it comes within 50 fps of 300 WM, which no game animal will ever notice. But since it uses a LOT less powder than 300 WM, you get recoil that exactly splits the difference between 300 WM and 30-06.

One reason I’m leaning towards the 300wsm is it’s lighter and easier to carry
