Tough question... if you forced me to pick only one, probably my Anschutz 64 topped with a Leupold VX-3 4.5-14X40mm EFR. But I use many different rifles and shotguns. My favorite shotgun is a Browning BSS Sporter 20 gauge that I had threaded for thin wall chokes... when we do our annual NorOnt upland/walleye trip, I bring the Anschutz or a Ruger 77/22 (stainless/walnut) and the BSS 20 gauge... it is a mixed bag of ruffed, spruce and sharptail grouse... limits every day, of both grouse and walleye... we eat good!
