Quoted from epthegeek:breath of the wild is a place you can LIVE for literally months and have a good time. I wouldn’t rush to Mario (no matter how good it is) until you’ve had your full serving of BoTW. Mario will still be around. Don’t rush. Savor.
Sounds like we're on the same page. I play Zelda games super thorough. I had found all but a few shrines and beat all but few missions before beating Ganon. Then I went back and found more shrines, maxed out my armor, etc. Then I downloaded the extra content. I just beat the master trials. I have one or two shrines I still haven't found and I'll pick up the rest of the armor but I'm probably about ready to pick up Mario. Zelda has been really really good. Like a lot of the recent Mario games, I had started to feel like they were just rehashing Zelda over and over and it had gotten corny with too much dialogue. This on was like a breath of fresh air.
