Neck and neck in quantity? No way. These IPs like Jak and Daxter, Sly Cooper (criminally underrated franchise), Killzone...great games but they don't have the track record (eg, quantity of releases) that the tried and true Nintendo mainstays do. Mario. Zelda. Kirby. Metroid. Pokemon. Donkey Kong. Fire Emblem. They certainly don't have the notoriety in hardcore or casual gaming circles.
As for a quality argument...if we're talking last gen exclusively, being objective about it, yes, Sony IPs have been of a higher overall quality than what we've seen on the Switch/Wii U. For every Breath of the Wild or Mario Odyssey, there was a Kirby Star Allies or Star Fox Zero. Expanding over the longer arc of history..Nintendo's got all the classics.
