I have both and the Kowa is optically better but if forced to chose just one for all my hunting needs I would choose the Leupold. As for the HD being worth an addition $100 - if you dont' plan on digiscoping I would say no.

Anyone who claims the 30-06 is not effective has either not used one, or else is unwittingly commenting on their marksmanship.
