Not really, they're both rated for -165 dBc, or something like that.
BUT, the 4.3-10 IS supposedly less dependent on accurate tightening with
a torque wrench (during mating with the female connector) to achieve
rated PIM results than the 7-16.
At this point in time I've done thousands of PIM tests on 7-16 based
transmission systems and have not found a big issue with inaccurate
torquing of the connector in the mating process, as long as it's been
tightened....well, good & tight. Problems are usually related to
improper installation of the connector onto the cable itself. Center
conductor too short, shield too short, improper coring, metal debris
left behind, etc.
Surprisingly, some of the worst problems have been with certain runs of
factory made jumpers, the manufacturer to remain nameless.

I REALLY like the fluted part of the female connector. Looks like it has a
better mating surface than the 7-16 does.
If you don’t get the 7-16 nice and tight, (with a wrench, preferably with the
proper torque wrench) they can really cause problems! Been there done that!
Does the 4.3-10 have a better PIM rating than the 7-16?
