I wish my MVP2 had the same controls as my v3. The v3 controls are more intuitive.
I felt the same way you did...Until I realized that the MVP does not have +/- buttons. It has p/u buttons. I like not having to use a two button combo to switch modes. Just push the appropriate button and it's in the appropriate mode. Then continue to push the same button to adjust the value of that mode. Kind of genius. That way I don't have to remember Hold down + and fire or hold down - and fire to change to the appropriate mode.
