Size of Otherworld and Excalibur Miniatures?

[Doc Twilight]

Hey, guys  -

Can anyone give me a heads up on the size of the miniatures produced by Otherworld and Excalibur? Specifically, I'm looking for alternative troops for the Angmar army I'm trying to put together for "War of the Ring", and I am wondering how they'd size up with the GW LOTR figs? I'm specifically looking at the Pig Faced Orcs from Otherworld and the "Undead Goblins"/Goblins from Excalibur.
