Which rifle for grizzly

[JO.]

I'd lean to the 325 just for the cool factor, but sounds like the Wby may be a better fit for the weather and conditions. Any major difference in barrel length on either? Muzzle brakes?

Need some input or advice.
Planning a grizzly hunt in Alaska, have two rifles I can take.
Both will shoot at .75 at 100 yards. One is a 300 Weatherby shooting 180 TSX. The other a 325 wsm shooting a 200 Partition.
I’m told, most shots are around 150 yards or less. They are pretty much neck and neck at that range.
Please don’t tell me to buy another rifle, even though I’d not be against a 375 H&H sitting in the safe.
Probably not, so just consider the two.
Thanks for any about any cal. rifle shooting 150gn bullet is plenty
