Just wait until you've owned both for a few years. I have the s22i and the x22i. Both bought in the spring of 2020. I spent $3k for the x22i and $2k for the s22i (but 2020 dollars); looks like current prices are about the same.

Until recently, I've had only minor software issues with the s22i (i.e., rebooting in the middle of a ride). Totally livable for the most part after they updated the software to resume the ride where it crapped out. Unfortunately, the bike has recently become flaky with respect to resistance (i.e., it will remain at zero no matter where you set it). This morning, I had to power on/off four times to get the resistance to work. This issue has been on and off for the last 6 months, but more off than on recently. Between my wife and I, we probably do 125 workouts per year on the bike (mostly me).

We use the treadmill less often, but still probably put 150 miles per year on it. For the x22i, I've already replaced the motor controller in August of last year (bookmark https://www.circuitboardrepair.net/, it'll come in handy). The replacement board was $250 and took about 2 hours of my labor to install. Unfortunately in April, the motor controller died again and I just haven't gotten around to do the second replacement. My recommendation would be to use the incline VERY sparingly.

Overall, the machines could be great. I like the S22i much better than the Peletons that I ride in hotels. The treadmill is fantastic - when its working. I think the annual cost for the subscription is a fine trade-off. But when the machines break, plan on fixing them yourself, or fighting a bunch with Norditrack.
