Not even close bud. Nothing is interchangeable between Howa and Rem700. Different triggers, different stock inlets, different action threads, etc. About the only thing they can share is 2 piece scope bases. The use the same threads and spacing for the individual front & rear mounts but the overall spacing is different so 1-piece Rem700 rails or bases won't work on a Howa.
Back to OP's question, assuming AP is the American Predator I'd choose the Howa HS for the much nicer stock. They'll both probably shoot about the same but having handled both I like the Howa trigger better also
