as the poster above said you can't really go wrong with either tub, they do have some differences as mentioned and the price will reflect that so basically it will come down to price and comfort...nothing wrong with the smaller tubs though, they heat up very quickly (when wired 220v), chemicals are easy to maintain as well as cheap on such a small body of water, and they only have 1 filter to maintain as well. Let us know which route you go and some pics are always nice...good luck
