I was faced with the same dilemma and eventually opted for a standard, glossy option. There's a lot of direct sunlight in my room, but "luckily" the temperatures in the summer get really intense over here (Serbia) due to the good old global warming and having AC on is not enough anymore when you get Dubai-style scorching heat in July & August, so I have to use the window shades to contain the sunlight coming into the room anyway, so a nano texture option would be a waste of money in my case.
Also, the degraded sharpness would probably irk me as well due to my well-perfected OCD and since I work with text and code most of the time, sharpness is really important for my use case. YMMV
