At 100 ft lbs of torque it’s solid enough to not matter with either style if dropped. As mrolen said, shouldered looks cleaner.
A Benchrest guy over on Accurate shooter had a very accurate shouldered barrel and it was shot as is, then the shoulder was machined down for a nut and the barrel shot exactly the same.
I’ve never liked the look of a nut, but forced myself to get one just to say I did and now I don’t mind them at all. For Tikka I’d just get a shouldered barrel, but for Remingtons a nut can save a few hundred dollars over having a short chambered or long shouldered prefit installed by a gunsmith.
A nut and specialized nut socket isn’t free if purchased separately, so be sure and add that in.
