We also own both a Model Y and an Ioniq 5. We've had them a little less than two years. They are both very nice vehicles with some significant diferences.
Ionic 5:
+ ride is smoother and quieter
+ build quality is better
+ nicer cabin in terms of comfort and style
- very non intuitive user interface - many confusing menus
- need to use ApplePlay for most entertainment
- no over the air software updates
- mid range model lacks seat memory and passenger seat is manual
- really needs rear wiper
Model Y:
+ superior user interface (yes, I'd like a few more manual buttons/dials)
+ many more customisable options for driving, comfort, and entertainment
+ Tesla Supercharger network - reliable fast charging
+ Seemlessly integrated Nav system, Spotify, Tunein, and many others
+ FSD capability: full self driving - we like it a lot
- cabin noise higher than Ionic
- need for service extremely rare but a PIA- can't talk to a human, must use clunky app for appointments
- build quality not equal to Ionic 5
