The Luscombe is no more difficult to take off or land than the Cssna 140 it's closest kind of trainer.
In the air the Luscombe is superior to the Cessna 140 in control response....there could be a problem for students switching from the Cessna 140 to the Luscombe with the braking system though.
The best tail wheel basic trainer I ever taught on was the Fleet Canuck.

Part way down this article is a picture of CF-EBE on floats.
I did my first solo on EBE on wheels at Toronto Island on August 13 1953.
