For many years I used to exclusively hunt thickets. 95% of my shots were coming inside of 15 yards, so that manueverability was the key issue. For that type of hunting the SQ2 would have to be the ultimate bow and at those close ranges the power isn't that crucial. But for any other type of hunting, for instance tree stand hunting in big timber, where a 30 yard shot is likely I would prefer the LX. Longer riser, longer ATA, and from all accounts a very stable platform. Also definitely more power than the SQ2.

I think the SQ2 is a special purpose bow. Can't you keep both?
