I'd say Xbox is the only of the big three that even can benefit from it.
Generally speaking it should be negative for everybody that production is slowed down, but on the other hand when the production of both new systems is slowed, it would always hit the one with the highest global demand (PS5) the hardest since it evens the scales to some degree, which is where Xbox has some potential to actually benefit by getting more market share. On top of that they also have the Series S, which isn't impacted to the same degree as the other new systems and therefore can also strengthen their market share because it's more readily available.
Nintendo isn't really in direct competition with the others, so even if they're in the best place atm of all three that doesn't necessarily mean they're benefitting. I certainly don't think they would be selling less systems if there wasn't a chip shortage, it's not like the pandemic were people are gaming more because of it.
