Whitebeard wins, with no prep or knowledge, Ulquiorra would likely come in close with his sword in an attempt to blitz.. Whitebeard has haki and good enough reactions to quake him if he gets close.
If knowledge, then Ulquiorra stays in the air and spams Lanza. I don't think that quaking a Lanza would be a good idea either because it could very well set off the explosion.
Ulquiorra dies, he starts out with in his base in character and has no prep, his only hope (spamming lanza from a distance) would require him to use his resurreccion right off the bat, be in an out of character mindset and start from a farther starting point, so WB quakes him until he's nothing but a puddle.
Callum Petch says goodbye to Screened by fondly reflecting on the site that gave him so much.
