I like scout rifles and scout scopes, but I also have regular scopes and usually red dots also ready to go in QD rings. My Steyr Scout wears its Leupold 2.5x Scout Scope mounted just forward of the ejection port just like it always did, and I can use it well after years of practice with it, but it's become more of a nostalgia thing for me than anything else.
With traditional scopes mounted on typical rifles, there are still many cases where a specific scope won't work properly on a specific rifle for a specific shooter. Slight differences in eye relief, available ring-mounting locations, variable spacing of free tube on scopes, and especially different shooter builds and stances all factor in; some scopes and rifles are just perfect for some people, and some...aren't...
When you start dealing with scout scopes and pistol scopes, the problem is magnified ten-fold. Many pistol scopes have too much eye relief to allow mounting them on many scout-type rails; they simply need to be positioned too far forward of where the rail ends on many rifles. Conversely, many so-called scout scopes have so little eye relief that they can't actually be placed forward of the ejection port, where a scout scope is "supposed" to sit, but that's just semantics. Scout scopes with shorter eye relief work great on things like leverguns or hammer-equipped singleshots and/or muzzleloaders, where they can be mounted just forward of the hammer, nice and low on the action while still affording a big field of view.
Trying to divide them up into categories of scout scope vs. pistol scope is tough because there is so much variation from maker to maker and even from model to model within the same maker's line-up. There are also scopes designated for shotgun use, which usually have a bit more eye relief than typical rifle scopes but less than actual scout scopes.
It gets funny when you start to read people complaining that their scout scopes give them so little field of view. The scope is way out there in front of you, forcing you to look through it at what is then a very narrow field of view...and when that image is magnified 2 or 3 or 4 times, the field of view will inevitably get smaller and smaller as the magnification increases.
There are simply too many variables for anyone else to tell you up front what will work for you. Prepare to buy/borrow/try a few set-ups before you find the "right" one. And then...prepare for your ideas regarding perfection to gradually be modified the longer you play with the scout concept. It's best to have 5 or 6 scout-ish rifles on hand at all times; that way, almost any scope you buy will work on at least one of them...
