I'm always been a Bushnell fan (3200's and 4200's) - and still am. I've got about a dozen. My FFL favors Burris so I bought one of them last year (an 8x32 Signature Select that's currently for sale). Recently I've bought several Nikon Monarchs, and they are okay. I also have five Mueller's.
So I've been racking up some bucks on the scopes (not to mention the rifles). About 3 weeks ago I needed another two scopes (I really gotta decide to stop buying rifles or forget retirement!), so I took a Bushnell, a Mueller, and the Burris and put them side-by-side at them same power and focused on a sprinkler flag 100 yards away out my sunroom door.
Honestly, for me I didn't see a lot of difference in clarity, field of view, or any other significant parameter. So I bought two more Muellers and saved several hundred dollars.
The nice thing about the Monarch's is the long eye relief - for my 308's and lesser calibers I'm not too worried about it. The other is the side focus, though Bushnell has those now too. I will say that the one negative to me about the Muellers is that the AO requires a lot more travel. But for bang for the buck it's hard to beat.
