I wouldn't call it advantaged in every respect. It has a shorter neck than it should and a belt. Both of which can be dealt with if you handload (neither of which have to be dealt with at all with the WSM), but with commercial ammo this combined with the shorter more efficient case design of the WSM means that the average WSM is probably a little more accurate than the average WM. And if you handload, it almost certainly has the potential to be loaded more accurately. Also, being more efficient means that it gets to within 50 to 100 fps of the WM with most bullets while using less powder. You may have the money to make this a non-issue. With the price of ammo and components now days, many of us do not and saving a few grains of powder to achieve the same result from a shorter, more efficient case that is less finicky and easier to load accurately makes sense. Additionally, recoil produced takes into account all the mass of the powder column and projectile, so from rifles weighing the same, the WSM will produce slightly less recoil to produce the same results. Or, if you hunt in the terrain I hunt in, you might appreciate dropping 1/2 to 3/4 of a pound off the finished rifle weight and still have the same performance and recoil of the larger heavier rifle.
Advantaged in every respect? Hardly. If you call less than 100 fps and the associated advantages in external and terminal ballistics, most of which aren't even appreciable on paper, "every respect," maybe.
But you are a fool if you can't see how someone would disagree with you on which cartridge is holding the better hand.
Keep in mind, I hunt with a 7mm Rem Mag. When the WSMs came out, I was in the same boat as you are. Then I started to look objectively at the chrono readings being published and consider how much I really did enjoy having to specially adjust my dies to work around the belt so I could headspace on the shoulder, and how much I really did enjoy using more powder than I needed to achieve essentially the same result, and how much I really did enjoy dealing with more recoil than I had to to achieve the same result, and now I am not so sure the WSMs are that bad of an idea. In fact, when I replace my current M700BDL, it will be with either a Browning A-bolt or a custom built M1999 in 7mm WSM.
So I hope you enjoy that 100 fps (or less) that your WM gives you because quite the opposite of holding all the cards, it's the only card it has.
