1. Properly applied, the crimp provides a gas-tight metal-to-metal seal.
2. Also, the ferrule provides a strain relief at least as good as the
braid-clamp in a conventional N or BNC connector.
3. For UHF connectors, double crimp = no heat and thus eliminates the
chance of melting the dielectric when used with polyethylene dielectric
cables.
4. I installed a batch of 50 SMA bulkheads connectors with 0.080"
diameter Teflon coax last year and it would have been a real challenge
with other than a crimp shield connector.
5. I've swept the crimp connectors I install up to 3 GHz with my VNA
and find them more than adequate in terms of return loss and through loss.
6. As far as longevity, I have some crimped UHF connectors that are 20
years old installed outside (protected with Scotch 33 electrical tape,
then self-amalgamating tape, topped off with Scotchcoat and they show no
signs of degradation.
7. Your opinion may differ and your standards for adequate return loss
may differ from mine.

I would add that once you have a good crimp tool, such as the
ratcheting type Don mentions, one can install crimp UHF connectors as
well.
I switched to crimp-type connectors quite a while ago and find them
superior to solder-type connectors.

uh pardon my ignorance...
since when is a compression styled contact point
*electrically*
superior to a soldered one?
at any frequency?
