There are a lot of airfoils with a L/D ratio over 50 - as long as you are just looking on the airfoil itself. Even an old one like the E603 will reach a L/D of more than 100, and to be honest, that's an out-of-date airfoil and can't compete with a modern one.
On a real plain, it depends on the aspect ratio of the wing, the shape of the fusselage, the wing tip...
