It is a tie, for me
One got Nintendo into game, one got them to a new level of innovation.
However neither has managed to maintain a solid relationship with the major 3rd party publishers. Yes I get it EA games, Activision, Ubisoft, 2K etc are not always revolutionary when it comes to making new games and are more known for rehashing material, but the fact is their franchises are mainstream and should be on a Nintendo console that is comparable to what other systems have, or at least up to the capabilities of the Nintendo hardware.
As for 3rd party indy? couldn't care less as most do not get physical releases, this is something Nintendo should also help out to get more sales and hep to these emerging developers.
Whatever future CEO manages to convince 3rd parties to actually try making a solid release will have my vote lol.
