I actually hunted wiith 2 guys this weekend, 1 had the sport stand and 1 the avery. The avery looked well built and very sturdy. The sportstand was lighter and easier to carry with decoy bag on the back. They guy with the avery stand actually lost a set of legs in the water at one point since they aren't permanently attached like the sport stand. The guy who used the sportstand sits on the the corner of the stand with his dog, but welded a tab on the inside so the combo weight didn't bend the ears on the stand.
Avery Ruff Stand works well.
