You should check out the TT 7-35x56, they sprinkled some kind of pixie dust on this optic as it blew me away with how much it could resolve and how bright it was at 35x, I talk about it more in my review here which reminds me I need to post a version to the Hide, just too many things going on.

I do like the March 1.5-15x42 FFP with DFP reticle a lot, but I can see where some might complain about IQ above 10x, for me it's fine, but for someone coming from a good 3-15 or 4-16 might be a bit disappointed, I think it is more about setting expectations, this is a 10x erector MPVO, something unique to the market and there is not competition for it and comparing it to a good 5x erector scope is a bit unfair, almost always the lower erector scope is going to perform better but it's also limited in it's magnification range so you have to decide what is most important to you.
I agree, March has the engineering prowess to make a scope that is on the same level as TT and ZCO, but their desire to make shorter scopes using high erectors has compromises which does affect overall performance. That being said, the new 5-42x56 Gen2 is very impressive with how well they corrected the soft periphery (edge to edge sharpness) and in that 10-20x Goldilocks range I would even put it on par with TT, ZCO and Schmidt but at higher magnifications I think the others perform better. My desire is to get the Kahles K540i (another scope where they didn't need to push the erector so far), the March 5-42x56 Gen2 and the ZCO 8-40x56 to compare with the TT 7-35 this year, time and funds allowing.
But we are deviating far from the title of this thread which is basically LPVO's.
I did a short review a few years back you might find helpful:
A crashed hard drive and another review has caused me to be delayed in providing more information on the 3 LPVO's that I had in hand last April. In December I ordered the Vortex Razor Gen III 1-10x24 in MOA BDC and after what seemed like forever it finally arrived in April. I bought my DT MDRx...
