I see no reason to limit float except for people who have a serious long term problem with the rear of their shoes hitting the crank or chainstay. First time Speedplay users often have a temporary problem with their heel hitting brushing against the crank but this usually goes away after a couple of rides.
I've had adaptor plate screws loosen but blue Locktight fixed that.
The adjustable float isn't the only difference. The clip design on the Zeros is different, which makes the engagement more precise feeling. I have both X's and Zeros, and I prefer the feel of the Zeros. They also seem less succeptible to debris, but neither pedal is great about that.
The price difference between an X and a Zero is only like $10, which isn't much. I think the two differences I mentioned are worth that $10 too. Don't get me wrong, the X's are great pedals. I just like the Zeros a bit better.
