Mirage Omni S10 or Energy S10.3 Sub?

[Bluray_ne1]

I have the chance to pick up either of these two subs for around $200 new. I'm upgrading from an old Energy eXL S8. There are probably better choices for a few more dollars (I'm really tempted to save more and get the ED A2-300 but space is an issue) but I still need to ask the question:

If someone offered to give you one of these two subs for free, which one would you take?

They appear to be very similarly equipped, both reputable names and both made by Klipsch. I've read so many posts, recommendations and reviews on the subject, my eyes are blurry. I just don't have enough experience with Mirage to know if either sub has the edge in quality and sound. I trust the many experts we have here to guide my decision.
