Zeiss is cheaper for about 100 dollars,
Which is would be better of the above scopes in low-light conditions and overall? A lot people like Zeiss glass quality, but will the Monarch Gold 42mm make difference compare to Zeiss 38mm?
Too close to call in all categories. You're paying a bit more for the slightly larger magnification range with the Monarch, but you're not going to notice a difference unless you have them both outdoors at the same time next to each other. You're splitting hairs. _________________ Aim Hard!
