I would suggest to wet test all three and make your own decision. What feels the best to you is probably what will make you the happiest. Hot tubing is as much a mental experience as anything else. Even if you have the best made spa, but there is something that bugs you about it (seating, jets, noise, etc.) you will not enjoy it.
Arctic and Beachcomber are good enough brands, don't know anything about the third one.
