I have March, Leica and Schmidt scopes on my main CF rifles and use Delta scopes on rimfires and air rifles. I would be happy using any of them on a stalking rifle as such if they offered a balance when considering some form of target shooting. I can say the Schmidt Polar is not actually on my main deer gun. It is actually on my .222 which is my most used rifle and the rifle I am most likely to be using in to the period where light fails.
I use the March on a .243 which is basically a middle distance pest control rifle or a fox rifle at night. It works brilliantly with NV add ons and dials faultlessly for those longer shots during the day. People always say the eyebox is fussy and it is not as easy as the Delta's for example but optically, when your mounting position is sound, it is very very good. It is not an out and out light gathering monster but you can crank it down to x2.5 mag which makes it very versatile for close shots and I have also used it on Muntjac in woodland. I rarely use it over x20 mag, which is the point where it becomes a fussier but x 20 is a lot of mag and fine for 99.9% of shooting. What I will say is that the reticule on mine (MTR3) is literally the best multi purpose reticle I have. It is thick enough to be visible but not so much that it obscures but you do not need to use illumination to see it against dark backdrops unless the light is really failing. The other thing to remember is that the reticule subtends correctly at x10 and at x20 mag and this is obvious as these Mag numbers are in red on the zoom wheel while all others are in white. I only use it at x 20 to use the ret for windage but it has open turrets, so I would dial anyway. The illumination is the best I have used. it is light, very light. It is small, very small. It is my favourite scope. The optic I have had the longest and I get through them, so that is saying something.
Here is a view at approx 225yds. The reticle is a bit out of focus and in reality when looking through it, it seems bolder and darker. It is my favourite reticle. The whole reticle (not the fat stadia, just the finer lines) illuminates via 4 touch push button on the side. Very intuitive and instant. No idea why all scope makers don't use this rather than the stupid illumination wheels. The worst being on the Polar T96 which annoys the hell out of me.
The scope I use on my main deer rifle is a Leica Amplus 3-18x44 with the newer windage reticle. This subtends correctly at x18mag which is fine as I would only be holding for wind at longer ranges where it would be likely I would be cranked up on zoom. And no need to make sure you are on an exact mag setting. Just crank it up to max and you know it is perfectly adjusted for using the reticle for windage. Elevation turret is open and easily dialled. The glass is good and it falls to the eye nicely as the smaller objective lets it sit at a natural height for me and my rifle. The reticle is finer than the March but not by much. I prefer the March reticle but this scope is a decent all rounder and nice and tough. The March is not quite as bright but is optically better in my view. Better colouration, better depth and better edge to edge and overall contrast. The overall clarity is better. Many people get hung up on overall brightness but optical quality goes deeper than that. March make very good glass. Mine is the 42mm, so the 52mm must be better brightness wise.
Anyhow, here is a view at around 275yds through the Leica Amplus. I think both of these scopes are nice and light and small but cover many bases without being perfect at anything. There is a Delta 4-24x50 Titanium HD on here with BT's that was going for something stupid like £515. I have no idea why it hasn't been bought other than people have no money at the moment. Delta make solid scopes that optically are really very good for the money. If I only ever had the Delta on a hunting rifle, I would never be disappointed as such.
