They are about the same, I have read studies saying both are better.
the only diff is cyp has an 8 carbon ester and eth has 7, so the half life is a bit shorter so it would cause a little bit higher level each day--about 2.8 extra per day, but the difference would disapear if taken on the same schedule b/c of the cum effect of the cyp releasing a tiny bit slower(e.g. 2x/week)
