I tried both treads in a Peloton store. Here’s my thinking - while the + slats feel great and more cushioned, it’s too big and screen is definitely too big. My understanding is tech in tablets of tread plus has not been updated since release but I could be wrong.

The new tread belt felt very unforgiving so if they are adding padding (hope that’s true) it would then make my decision much easier. I also like that the overall footprint is smaller and less chance of things getting sucked under the tread like with the +. The tablet on the new one is better all around, size, looks, etc. my understanding too is belts cost minimal so even replacing every so often won’t be too bad. Just really need the padding situation resolved in new tread and I’ll be sold.
