Would the Axis have fared better or worse than the Allies did in an Operation Neptune style offensive?
worse due to not having control of the seas or air. The initial landing troops would be cut off from the sea by the Royal Navy and then pushed into the sea by better supplied troops with armour in Britain.

Considering they lacked any sort of landing craft at all no. For Sea Lion they planned on using towed river barges and underwater tanks to land on the beaches and unless they can then quickly secure a port they have no way to supply the landed troops
