Jacuzzi vs American Stand. vs Maxx Whirlpools

I need to order a corner whirlpool tub for our master bath. I was ready to order the Maxx Advanta Cocoon tub but the fact that it has a 3/4 HP pump is a concern. All three tubs are acrylic and have a comparable number of jets but the Jacuzzi one (from Lowe's) has a 1 1/4 HP pump - I haven't checked the American Standard one yet.

I can't find reviews comparing these whirlpools, I don't know what an industry standard is for thickness of acrylic or pump HP per number of jets and I'm getting concerned that I'm going to end up with a problem later.

Can anybody help me choose? Thank you for any help!!!!
