Kadaj's ability to directly absorb Jenova is evidence of that.
And, by the way, Kadaj's absorbtion (is that a word?) of Jenova's head (the literal translation of the Japanese is of course neck, but I'll just stick with head to avoid confusion) is what turns him into a complete being. He is Kadaj in larval form, then the Jenova cells cause a metamorphosis within him, turning him into the fully grown Sephiroth. Thus, Sephiroth is at least three times better than each Shinentai (Kadaj, Yazoo, and Loz).
However, we must remember that Sephiroth is greater than the sum of his parts, thus he is vastly superior to all three Shinentai. Not to mention that Kadaj was an over-emotional teenager, Loz was an absolute cry-baby, and Yazoo was useless. Sephiroth was far above all three of these things. And whoever says that Sephiroth is a one-dimensional villain seriously needs to play that game again.
