I like to shoot primes wide open very often, and with 35mm f1.8 G it is possible, but with 50mm f1.8 D it is not because it is very soft wide open, so I would suggest to add more money and buy G version of the lens, it is much sharper wide open.
Of course, D lens does not have distortion at all, while G version has. It can be important for some video work.
