Whitetail are a bit smarter then a mule-deer so offermore challenge.
but I love Mule deer hunting two . Note I still stalk both breeds, no blinds,no stands, no bait. I would say for me it would be whitetail,I have hadthem bucks do somepretty sneaky crap on me. " keeps it fun when their not dumb"
Note I could rise from the grave to go Elk hunting that is my calling..
