I love my Athena because it's perfectly smooth and the shape is perfect for me. But it's pricey. Still, it was my first and I couldn't be happier. I saved points for it for quite a while and did a buy out. So worth it. But that's just me. None of the other smooth toys appealed to me, but the Bent Graduate and it's many imitations seem to be a popular choice, especially for the price. That bend it just a bit too extreme for my anatomy.
