I just purchased a wifi version of the IPP and I was wondering who has had an LTE version that opted to tether with a wifi version instead? I'm not sure if I should have purchased the LTE version instead.

I was wondering the same thing. I just my second iPad Pro (returned 12.9 2gen for the size). Went with the 10.5 256 wifi mostly for priced. Figured I'd just have to up my plan and just tether instead of upping my plan AND paying the $10 add on with AT&T.
I'm actually on my way now to exchange it for the cellular version. Makes more sense to have it and not need it all the time. It kept me up all night tossing and turning lol. It's only 10 a month on AT&T anyway.
I'm typing this on my new cellular version iPad now. No regrets at all. So happy I made the switch.
Awesome. It’s the only way to go. Unless you never took your iPad away from the house. And it sounds like you take it out. Great choice. You won’t regret cellular.
It's such a great feeling after popping in the SIM card and seeing the LTE at the top corner. Also coming from such an older iPad, the screen is so brilliant. I'm like a kid at Christmas right now.
