Nintendo is successful because of their games, not because their hardware is the best
I agree, their first party games are usually extremely polished and accessible for everyone in the family. their concepts overall for consoles are typically really good though. just about every console since the Wii (except WiiU) has felt great to use, even if they all have some kind of gimmick. But I think the gimmicks help in their favor, it makes them stand out from PS and Xbox
