I don't think I'd agree that all speakers are equal for HT.
A common problem with cheaper/smaller sub-sat systems is that the small midwoofer in the satellites can't go low enough to properly blend with the upper range of the sub module.
Of the ones you list, I've heard the Energy & the Athenas. Both were okay for the price, although the Energy exhibits this "hole in the bass" a bit on music. For primarily HT, though, they're fine.
I've heard raves for the Hsu Ventriloquist rig, and it would be in your price range with Canadian exchange (what's the rate right now, like 70% or so?).
Be forewarned that asking what speaker is best is like asking someone what your favorite food should be. We can make suggestions, but ultimately you may like something else. Best bet would be to try to buy from a place with a liberal return policy.
