The normal red blood cells would be better because sickled red blood cells clump and are not circulated as well as normal red blood cells are.
Normal blood red cells are biconcave disks, approx. oval.
The genotype of a person with normal red blood cells is usually AA, where both copies of the beta-globin gene are normal. This results in the production of normal hemoglobin and red blood cells.
when a person has fewer red blood cells than normal his or her color is yellowish

red blood cells
A drop of blood contains red blood cells, white blood cells, and platelets. Red blood cells carry oxygen, white blood cells are part of the immune system, and platelets are involved in blood clotting.
size of red blood cells
Theyhave some normal hemoglobin in their red blood cells.
Sickle cells have an abnormality in the oxygen-carrying protein hemoglobin. Functionally, sickle cells are more rigid than normal red-blood cells. This can result in them getting "stuck" in capillaries because they don't deform as well as normal red-blood cells to allow them to flow through the capillaries. The sickle cells also break down faster than normal red-blood cells - due to their decreased elasticity they are more prone to "break" when trying to deform to flow through the blood vessels and capliaries, leading to anemia.

Polycythemia is the condition of excess red blood cells in the bloodstream. In contrast, anemia is a deficiency of red blood cells.
