It's usually other way around.... as in student learns on Warriors, then wants a get-lost-quicker machine so upgrades to Archers...
Speeds are essentially the same (certainly at Barton they quoted as the same) apart from cruise & higher speed limitations.
Warrior props usually better for circuits than cruising so you may (if your Archer had a cruise prop) notice perkier acceleration and climb performance but lower s&l speeds for revs.
..and the Archer fit is usually more luxurious so it will seem spartan unless it's someones pride n joy...
