There is a comparison at

Since Levitra is still under patent protection all alternatives that contain vardenafil are not licensed and there is no way of knowing exactly what the tablets contain.
On the other hand the patent for Viagra has expired and licensed generic sildenafil is available at a much reduced cost.
As for which is more effective the only way to know is to try each one in turn and evaluate the outcomes.
Everyone is different and some may respond better to Viagra while others may find Levitra more effective.
