The Allisons have the advantage of already being in your possession, but... doesn't that model have the top facing woofer? It has more specific placement constraints if it does, plus can't stack stuff on the top surface. Good botton end on all Allisons I've heard. Large Advents, good luck finding a pair that still work (foam surrounds) but if you can, they will certainly handle the bottom end. Not familiar with the other two. If you are shopping, and want to keep the budget under control, don't overlook Polk. Been around forever so a good used market.
