I have an 8x42 MHG and It is quickly becoming my “go to” birding binocular. They have a lot going for them - very crisp and vividly detailed image, expansive FOV, very good color, very bright, the focus is a good speed, and at just 23.5 oz they handle more like an 8x32. But don’t be fooled - simple physics give a 42mm binocular an inherent optical advantage over a 32mm glass. I also have the much lauded Zeiss Victory FL 8x32 and it is a spectacular 32mm binocular. But as an everyday glass I prefer the overall package of the 8x42 MHG. They do have a few negatives that I tolerate because of the many things it does very well. I don’t like the diopter as it is too easy to accidentally unlock, the accessories are very basic for a binocular in this class, and the leatherette armor only covers the majority of the barrels - which I believe is more for grip than protection.
The Trinovid is no slouch - upon picking it up this binocular appears very robustly built, the image is very sharp and bright, the color is very true, and all of the mechanics feel precise - IMO the MHG might have just a smidge more CA in the brightest light. The FOV is noticeably narrower than the MHG but in addition so is the “sweet spot.” The Leica has more lens curvature and off-axis aberration than the MHG. The Leica is also heavier in the had than the MHG. But Leica’s warranty and customer service (much improved in recent years) is far better than Nikon.
