Lay waste has such a small area and the delay makes it unlikely to hit anything but the primary target, does low damage and rapid mana drain. Its range is shorter than most skill-shots.

Defile does more unambiguous damage because of its area, but its centered on Karthus.

Experienced teams should know counters to Suicide karthus.

Athene's unholy grail grants 15% mana when you kill or assist a target. Morellonomicon applies a healing debuff when the target is under 40% health.

I prefer Athene's as it raises mage sustainability and for Karthus it feels necessary as he isnt a nuker with big attacks, but a spammer that chips away with lots of little damage.
