Besides appearance, what are the practical differences among edge styles for laminate kitchen countertops?

The local big box stores stock countertops with ogee edge, a "waterfall" edge, and "no drip edge".

The ogee edge looks nice, but is there another reason people like it? It seems like the little lip on it just wastes countertop space.

The waterfall edge (round, with laminate on the underside) might let water running off the counter run down the face of the cabinets.

The "no drip edge" ( half round , with no laminate on the flat underside) is more likely to keep water off the cabinets, but the particle board underside might get wet and deteriorate.

( An interesting policy at local stores is that they don't stock the same color/texture countertop in two different edge styles. Perhaps that's to head-off the problem of accidentally filling an order with pieces that have mismatching edges. )
