What are the two major differences between spermatogenesis and oogenesis?

Spermatogenesis vs Oogenesis

Spermatogenesis Oogenesis
Produces motile gametes Produces non-motile gametes
Equal cytokinesis occurs during the spermatogenesis producing four sperms Unequal cytokinesis occurs during oogenesis ultimately producing one large ovum and tiny polar bodies
