If I have to choose, I guess I'm picking Mario Kart World (disclaimer: I haven't played too many current gen games yet). Despite some things not being quite right for my personal taste (somewhat lacking character selection, battle mode being a joke, free roam needs to be A LOT more fleshed out...), I really enjoy the more open nature of the game (24 racers at once, I actually like intermission tracks, all the crazy stuff you can do with walls and other track elements is great), the soundtrack is absolutely insane and a huge tribute to the Mario brand in general... and while I think character selection itself is a bit lacking in terms of actual named characters, costumes are awesome and I like being able to play as some of the background characters. Also, both the new tracks design and the classic ones are very, VERY good and imaginative, easily being on par with the best of MK8 and Wii (my personal favourites as far as track design is concearned) and sometimes surpassing them.
It's a game I see myself coming time and time again for the entire Switch 2 lifetime. I guess that speaks volumes about how good I think it is.
