SMA: Fine. The one-part type is good. The two-part type with a pin assembly that screws into the outer shell is worse because it’s easy to unscrew the pin by accident.

RP-SMA: Fine. Like SMA, but invented for a dumb reason. Whatever.

MMCX: Fine. Satisfying to connect: they snap in. Some cheap ones fit loosely and wiggle around which is… probably not great for signal integrity? Use the good ones.

FAKRA: Fine. Industrial strength. But watch out: the latch eats thumbs.

U.FL: The devil. These little crap pieces are fiddly and fragile. Use anything else.
