Nitrous cam exhaust lobe profiles

Who on here can tell me about choosing nitrous ex lobes ?
Here's the deal , I'm looking at exhaust lobes
One lobe  is 333 on the seat 297@.050 and 208 @ .200 lift
The other is 332 on the seat 298@.050 and 214 @ .200 lift
Is the slower ramp lobe better for nitrous or the faster ramp
Better for nitrous , some one told me the faster ramp lobe will get it
Out quicker and someone else said that the slower lobe will keep the valve open longer
