I have not been around all of these scopes but I have compared my Bushnell Elite 4200 and 6500 to Black Diamonds and various Leupolds and I would definitely keep my Bushnells. The glass is awesome and they are supposed to be very good at holding zero especially in situations like you are going to be in. Mine are perfect at holding zero.
