Personally, I prefer the feeling of no grips and I think you get a cleaner release. I can't go no grips though, because it's always torn up the sides of my fingers. I know for most the opposite is true in terms of finger wear. I just use the oval vise finger grips and it feels the same.
If you going from the power lifts to ovals though, it will feel like your losing the ball at the bottom, but you'll see that the ball still hooks the same and you experience a heck of a lot less grab. It's a better combo for tough patterns.
