I believe I've only ever dated NTs up to this point, but I know plenty ND people. It's a mixed bag. Everyone will bring something different to the table and you just have to find something that meshes well with you. Some of my ND friends I would not fathom living with, let alone a romantic relationship, but same could be said for some NTs.
Someone who is understanding of you and respectful of your needs (and you theirs) is what a healthy relationship demands, that is not exclusive to NT or ND. Some people may jive better or have weaknesses covered by someone of the opposite, or of the same.
