I was using 05 on my forehand and 64 on my backhand , coach changed to 64 on both sides.Has improved my consistency and hence the level a lot. Definitely there is no rubber with the best mix of speed and spin than 05 but if you want more control i would suggest 64. Closer to european rubbers ( softer ) than others because of the spaced out pip structure . However, I think the size of the pips are larger than 05 ( if i remember correctly , a good place to check this is the butterfly website ) . But loses its pop quicker than 05 because of less support. Good overall rubber for all round game. What else do you want to know ?
