I use the ATVs over the Clevelands for a couple of reasons.
Firstly I have always preferred the 100, 75, 50 set up over the 100, 80, 60. I feel that set up covers the all yardages from 105 yards down to zero with full and punch shots and variance in spin.
The second reason I use them is that I feel the spin control is much easier to learn and become proficient with. I particularly like the way they play when pitching and as a result always feel I have a good chance of holing out from just off the green.
Clevelands are probably a percentage more accurate and have more spin but I found them much more difficult for nailing down my distances and spin control.
