Ruby Sightstone is "crap" intentionally. If you get one of the other upgrades, you lose out on whichever    you would get by purchasing Ruby Sightstone with that item. With Ruby Sightstone, you can get an AoE movement speed buff, a shield for an ally, or an auto-targeted long-range slow - plus, they're all on a lower CD. The other upgrades don't allow you to have that in combination with a Sightstone item, and because of this are more powerful than Ruby Sightstone on its own.

Think of it this way: Talisman of Ascension plus Ruby Sightstone is way more powerful than, but they take up two item slots. Eye of the Equinox is more powerful than Ruby Sightstone, but then you are unable to get Talisman of Ascension's powerful active.
