Unless you specifically need the elongation that XSeries offers, I would not recommend it over the 3DM-ABS.
3DM-ABS is extremely easy to print with because it both cures fast, has high detail, and sticks very little to FEP film.
3DM-XSeries is not as easy to print with, and is also more than 50% more expensive. In particular, XSeries sticks substantially more to FEP film and can’t quite hold detail as well.
Solid high surface area parts, in particular, are fairly easy to print with 3DM-ABS, but may be difficult to impossible to print with XSeries without hollowing and rotation.
