Having a Creed I too would opt for the Nosler. Not because of bears, just not enough difference between the Creed and the PRC. I shoot the PRC and 260 Rem, but I have 4 kids using rifles all the time so a little expensive overlap is a good thing.
I'm shooting the 140 GC serria's at 3140 with Rl26 no pressure and the 91/2m's are still tight after 4 firings. Normally I have to switch to winchester or federal primers after 2 or if lucky 3 firings loading to 3100fps/H4831 or 7828I'm happy with my PRC and I personally believe either would fill the role you have laid out. I kind of view it as a .270 with a little extra and better bullet selection. 140s at 3050-3100 would be a stout 270 load. I wouldn't hesitate to take a 270 out for mostly deer and some elk, don't see this as any different. At the end of the day being able to shoot well with a rifle matters the most.
A couple other things to consider that may help you narrow it down:
Do you hand load?
If so, compare bullet options.
Are you recoil sensitive?
Might need a heavier rifle for 28 nosler if you are.
Barrel length/overall length for each. With the short action you can get a longer barrel at the same overall length. Etc
