If you read my original post you'll see that I never referred to White as an Arrancar, but an experimental Arrancar and I'm sure I didn't refer to White as anything else in my following posts.

The definition of an Arrancar is: "A Hollow that has removed its mask and has gained Shinigami-like powers." The Hogyoku is not required to create an Arrancar.

When I say White was an experimental Arrancar I'm looking at the vision Aizen had and his attempts to overcome the barrier between Shinigami and Hollows and create a being with the powers of both sides.

Instead of a Hollow cracking its mask to gain Shinigami-like powers, White was created by placing a hollow into a Shinigami corpse to achieve similar results. The latter technology was flawed, so Aizen used the former to create his Arrancar army.

Isshin probably said that White had a Hollow's reiatsu because the Hollow was in control of the Shinigami body, much like the Hollow is dominant in Arrancars.
