Nits = how bright can bright get? If you want your sunny shots to be searingly so but your dark shots to still be clear the ideal is to have high dynamic range: really bright brights and really subtly dark blacks. If you don't have the former, you compress the likely dynamic range you can display under daylight conditions. So a high nit display (with HDR) can "wow" both with total brightness capability as well as broad dynamic range.
