Which would you choose and why?

Neither, I have a takedown 450, Marlin and a Norinco
12 ga( 3" mag) single shot.It might be 25" long .
Both fit into my army style ( deep) saddle bags or into a human pack when afoot.
I see Grizzlies frequently, even at my Ranch.
I had one encounter with a sidearm, a .44 mag...after that went back to the rifle and 12 ga.
The .44 might just make a bear really mad.
