well you understand the pain better, so I suppose that makes it less painful.
Difficult to say, you know how you forget the pain after you've got your little bundle of gorgeousness.
But, if it helps, with dd1 I had gas & air, pethidene, epidural and still screamed blue murder.
With dd2 I had a teensy bit of gas & air then decided that I didn't like the way it made me feel so made do without.
Ds was an ecs so never actually laboured with him.
