I know Bowser's Fury is too small to count as a full 3D Mario but I love it.
I also love Odyssey, enough to get all dem moons. It's one of the games I often keep installed on the Switch for a quick playabout (usually on the moon for that gravity fun and that celestial serene vibe, but also often in the gardens for the music (though level wise it's a bit stilted and broken up for a proper runaround).
I do Not play Mushroom Kingdom much though. Something about the sound echo makes it feel very eerie and lonely to me.
