I shot both when I was trying to decide too, and I went with the Stealth NXT. I couldn't justify the (then) $400 delta on the price when both were shooting at pretty similar speeds. TenPoint advertised the Stealth as their most accurate xb in 2019, and at that time they advertised the Nitro as their fastest.
In my opinion, you're splitting hairs on both accounts--both are super accurate and super fast. Both are also high-maintenance items in terms of strings and servings... I have committed myself to sending mine in to TP every couple of years for a tune up and new strings/servings because of that. This is, however, likely going to be the case for nearly all of the super fast, super narrow xb's out there today.
The real difference is whether you want to get in on the reverse-draw technology, or if you're happier to stick with the more traditional design that's been around longer. You can't make a wrong decision between these two crossbows!
