They are both Pre-War Mausers of the highest quality originally, not much different except for minor fittings. Most have been also heavily aresenal reworked. Function and quality are toss ups in my view.
So I wopuld go for the one that seems to have survived in the best shape.
Beware of pitted bores and chambers, cracked stocks, corroded barrels and recievers, nasty triggers, loose sights, evidence that someone has used it as a crow bar and, in genaeral, look for signs of all around abuse. Always have your rifle head spaced by someone competent, as a lot of these fail that test.
Thats why I like to see these in person before commiting to them. I would, like I say, look for one of the nicer examples of either.
And if you find a nice one, think about avoiding corrosive surplus ammo. That has done in the bores on a lot of these, so why ruin one of the remaining nice ones? You have to be much more vigilant about cleaning with this stuff than most people actually are. I guess most of us are spoiled by half a century of not having to worry much about this.
