The .300 Winchester magnum will always be "more" than the WSMs.
My SAKO 300 WSM feeds just fine. The rifle doesn't shoot worth crap, but that's the cartridge's fault. Install a centerfeed mag box with a flat follower and good to go.
It's true the 300 WM has about 9% more capacity but for guys like me who do not care for belted mags, the WSM is a nice option. And they have indeed become popular in the BR world. Also, the 300 WSM is very capable of shooting bullets up to the 215 Berger Hybrid. I have shot the 210 Bergers @ 2930 with RL17 out of a 24 3/8ths barrel.
As far as finicky to load for, I do not buy into the thinking that case design equals better accuracy or less finicky to load for. It may be the case for your particular rifles, but there are a lot of accurate shooting WSMs out there in various calibers. IMO, it's the rifle components, smithing and load development that make the difference in accuracy.
It comes down to what fits a a particular persons needs and wants. Sometimes less is better if it meets your needs.
Marketing ploy or not, the WSMs are a good cartridge and fit a niche with a lot of shooters.
