Propellant volume, mass, complexity and difficulty of maintenance put NTR engines at such a disadvantageous position that it will be difficult to find missions that justifies their usage over methane engines.

That is generally my belief - they are mostly in the "wouldn't it be great" category.

I do support the NASA program because there's an open question as to practicality of NTR engines and I think settling those kinds of questions aligns well with NASA's charter.
