Which treadmill/app combo provides the best immersive experience?

Which treadmill / app combo provides the most immersive experience?  Similarly, which app provides the most fun experience? (answer might be the same for both)

Which app to use, depends on what you’re looking for and on who you ask. My two cents (which may be very different from the next person’s.) Do you want guided outdoor scenic runs? iFit is your app with the NordicTrack x32i or x22i treadmill. Do you want a powerful studio running dance party on your treadmill? Peloton is your app with the Peloton Tread. 
Again this is all subjective. I’d suggest downloading both apps with their free trail offers and watching a few classes on your tablet at your local gym. That’ll give you a feel for their differences and lead you to the treadmill that best supports that training app.
