By last gen do you mean Wii U/3ds/vita/PS4/Xbox One? If so, you didn't think Spider-Man, Mario Kart 8, Zelda Botw (was a Wii U game originally before Switch was rushed out) were great? I'm sure there were at least some great games.
But yes, I do think this generation is starting off better. Took Switch a while to work through the Wii U Potts, but since then has produced some absolutely fantastic games and PS5/Series XS seem to be off to a great start as well.
Its easy to not think of Nintendo when thinking of a gen. But I guess I meant a last gen as 2014. First year of playstation 4 and xbox1. I wad comparing both first year not the full gen to the first year of this one. Would make no sense to do so.
For me it's impossible to not think of Nintendo when thinking of a gen. They make some of the greatest games each generation.
