Try the Mark 5HD 3.6-18. Cheaper than both, decent glass, and right in between on weight (26oz). I’m not sure that it is necessarily better than either, but it’s not a bad choice.
I was considering a March as well but the shallow focus / parallax that I saw Ilya and others mention put me off of that idea.
MK5 is garbage. I had that very model and it went back to Leupold for re-work. When it came back it got dumped and went with a NF ATACR. A few ounces is worth reliable repeatability. Gun is already light enough and most that hunt with it only carry it short distances to their blind or stand.
