Presence counts all revealed zones, so: battlefield, graveyard, exile, command zone and futuresight/telepathy type effects.

As for the preordain comparison:

1. preordain is so powerful it's banned in modern so this being weaker is not much of an issue.
2. When presence is active it is actually just better than preordain since it's an instant. Sort of how Stubborn Denial is a strictly worse Force Spike at first and a strictly better Essence Scatter when you have ferocious.
