First off welcome to OT
Your call. I generally like Leupold stuff. One of my favorite binoculars is the Mojave 8x32. However the 8x32 has the new features the 42 and 50 mm sizes won't get until later this year.
I have a friend who has the 12x50 and I do not like it much, but he does. His dad has a place in South Dakota and he likes it to hunt there in the wide open spaces. The ergonomics, image and build quality are fine, BUT, and there is always a but, and this one's a deal killer for me, is that there is an excruciatingly narrow obvious field of view. Lots of tunnel effect and it looks like you are looking through a couple of long paper tubes, kind of like a decent image at the end of the tunnel, not up front where it needs to be.
I generally will have nothing to do with recommending anything over 10x, but eyes vary and what you see through a 12x50 Mojave may differ from me.
