No they won't handle exactly the same. Many of the forces acting on the steering are dependent on the head angle as to how they effect the steering. So a side force acting through a 73* HA and a 70* HA will have differing resulting steering effect.
But this begs the follow up question as to why a rider would want one geometry or another one. When I design a frame what tire sizes, fender clearances, load/weight balance the bike will see are very much a part of the geometry choice.
Since so many of my frames are on the short end of the bell curve I've found more need to kick out the front center (given the short TT) then many who build larger frames do. A slacker HA and more rake gets this done. Andy
