Is it for deer, or fox ?
For deer, neither, the field of view is way too narrow, and makes spotting hard work, especially if you stalk in woodland. I had an XQ50, sold it almost immediately, hated the narrow field of view in the woods. Switched back to an XQ38.
For fox, personally, I would also favour the XQ38, or for a budget option, also very compact, the XM30, but the field of view is narrow. Axions are ok on open fields.
