I purchased the Slash II because at the time I only had 20hp and needed an energy efficient tube = more speed. It's fantastic, glad it's a U shape as it still proves difficult to get back on after being dumped. Steering ability makes it more interactive and fun, you can be more aggressive crossing the wake. It's very well made. Only criticism is that once unpacked it will never ever go back into the supplying box. Have no clue about the other model you state, let us know if you buy it.
