Choosing between only those 2, I'd get the 4200. I just am not crazy about the low end Leupolds. If I was considering a Leupold, I would start at the VX II and go up from there. I have a 4200 in 6-24 X 50 and it's great glass. I mostly put Burrises on my hunting rigs though. Nikon Buckmasters are great too. I would rate these scopes as follows for hunting rifles. 4200 is best but overkill, Burris FF II, Bushnell 3200, Nikon Buckmasters, and Leupold VX II are all tied for second in my book and the VX I and Rifleman are tied for last.
