Cams choice, Low CR vs VE%

Draw that out on paper.
What you are proposing, is basically a difference in clearance ramps.
The lift after .050 can be manipulated by the camgrinder who knows his equipment, to fill a marketing need, or a perceived need for the combo.
If you gotta blow off some pressure, you might choose the long ramps,
if your pressure is already low, you might choose the shorter ramps.
If you have lightweight solid lifters, you could put some decent area under the curve.
If you have heavy-weight,retro-fit, Hydraulic rollers,you might get into trouble over the nose, so you might have to sacrifice rate of lift.
If you are drag-racing, you might go crazy on the rate of lift, knowing that the cam might not last very long.
As a streeter wanting long life, you might choose a slower,more durable rate of lift.
If you have a small engine, and want to prove a point, you might go both-feet-in, and choose the most radical rate of lift possible.
If you have a stroker on the street, you might choose the laziest rate of lift.
So there are as many ways to grind a cam as the grinders have lobes in their catalogs.
