Type N is weatherproof, BNC is not.

Type N peak voltage is 1500 V, BNC is 500 V (UHF is also 500 V).

Type N rated to 11 GHz, BNC to 4 GHz.

Type N RF leakage -90 dB min @ 3 GHz, BNC -55 dB min @ 3GHz.

For this kind of thing, I go to the Amphenol spec sheets for connectors. The specs for the UHF connector are minimal, three specs for electrical, no mil specs.
