Welcome to our forum.
TTodd1, It is interesting to see that we have different opinions on certain features in the same spa, just goes to highlight how really personal the decision on a spa selection is and how important it is, as you have advised, to wet test.
ttodd1,How tall the users will be may be part of the answer, I am 5'8" and wife is 5'1". Wife actually finds parts of the Optima too deep for her so we will be getting one of the "booster" seats. . .
