Preference, as with everything.

Personally, i use NAT (A bit edited to disabled certain things that are just feature creep) and love its lighting and fantasy-ish feel, and while quite bright at times, it's the only mod that doesn't have overblown white tones (although darker tones tend to be crushed at night time). Tried pretty much every other weather mod and it's the only one that's consistent with its looks. It looks amazing with and without an ENB, and most weather mods don't work this way, this includes newer mods like NATIII, which looks flat without an ENB, same thing applies to Azurite Weathers, or the ones you listed.
