Tough choices indeed. For me it would probably about wringing the plane out in low altitude aerobatics, so jets/rockets would be out unless it was about pure acceleration/speed. Top contenders for the aerobatics side of it would be Fokker Dr1, Bf109 (F or earlier model), FW190A. If it was about acceleration/speed Me163, F-22 (or whatever is the highest thrust/weight modern jet) perhaps even x-44 manta. In the end I think the Dr1 would probably win.
Not sure why anyone would want to blow an hour in a space shuttle or SR-71 those seem kinda boring honestly.
