Switch's first three years have been good across the board (crap first quarters in every year apart from 2017 though). 2019's been my favourite year so far games-wise, DQXI and FE:3H were absolutely fantastic, and Tangledeep was great as well.
It's currently my second favourite system ever, to overtake the DS and nab #1 it needs 2 or more of the following for me: Pikmin, another mainline FE game, another mainline DQ (a remake is acceptable for both DQ and FE), a PMD: EoS remake/new entry, Mother (1-3 remake, or a new story), Chibi-Robo!, a new mainline Pokemon (improved from SwSh, with a lot more content), a Mario RPG (don't care which flavour), a new IP that grabs me.
I think it's definitely going to get there by the time all is said and done.
