Float is much better for your knees. Even if your cleats feel fine in their position on short rides, damage is still being done! Putting that much force through your knee joint at a different angle than the joint is designed to operate causes uneven wear as the force is focussed on a smaller surface area.
I suffer from juvenile arthritis and my physio advises me that if I still want to be walkenging in 20 years I'd better switch to more float in my pedals and raise the inner-leg sides of the sole to further mimic the force vectors of walking and running.
