I assume you mean ACS replied as Tayside uses Aquilas and Warriors (at Dundee anyway).
Tayside’s a good outfit and Dundee Airport is quite a commercial environment to learn in with full air traffic control, instrument approaches and airline operations (Loganair). Perth is more of a flying club airfield with microlights and autogyros to share the circuit with, so to some extent it depends on your long term plans.
But Dundee and Fife are closer to you which is an advantage, all other things being equal.
