Have you looked through one at a 900m target Jerry? I like my Sightrons, but if I could justify the extra spend I would switch in a heartbeat.

Yes, I looked through them while I was at Nokomis a few Westerns ago and a local shooter has a few that I sneak behind whenever I can. There is no doubt the image is clear but like everything, at super high mags, the image drops off. I would definitely have no need to use 60 to 80X even if the air allowed - way too easy a chance to cross fire especially shooting off a bipod.
At the mags I typically want to shoot at - 35 to 40X - they were certainly clearer then the Sightrons and NF scopes BUT what I didn't like about them was the reduced info from the mirage. Part of the perception that the image is "clearer". This difference narrows up dramatically in dry mirage free air.
Here the Sightrons definitely agree with my eyes more. I want to see the mirage and the more info I can get, to a point, the better.
All the scopes had no issue seeing target spotters, target lines or hindering me from adjusting aim in small increments at 900m. Just the amount of mirage info differed.
So, for my tastes, I see no benefit to the March. If I were to get a March, I would certainly add a spotter to make sure I could see the mirage as much as possible.
Where I think a March can be of slight benefit is in team shooting. Here the shooter is only concerned about a precise hold that is indicated. With a "cleaner" image, that precise aim is easier and faster.
Had a nice chat with some overseas shooters on this as their team shooting was all with March scopes. However, a few indicated they preferred using the Sightron for individual shooting for the same reasons as me.
So personal tastes will play a large role in the "better" part of this comparison for LR F class.
More thoughts on strategies and pros/cons with optics but that has nothing to do with this post so give me a PM or email and we can chat more.
