I tend to agree with Danny on this one.
I haven't broken an SMA connecter yet, but I've known of many instances 
where this has happened.  Far fewer instances of BNC connecters breaking off 
the radio or snapping.
Also, BNC connecters are far more ruggedly constructed and due to their 
larger size, are far easier for blind ops to repare than an SMA.
Also, a female BNC, IE the connecter on the radio itself, has far less 
friction on it when taking antennas on or off...an SMA style set up requires 
you to screw the antenna on or off the radio, and the center pin of the 
antenna, or at any rate, the male part of the SMA connecter drills into the 
female part of the plug until the connection is tight.  This causes metal 
fatigue.  With a BNC connecter, you just press the two halves together, and 
give a quarter turn and it's done.
far far less stress on the electrical connection point.
Perhaps the BNC might endure more strain or stress because it sticks out 
further from the chassis of the radio, but this is compensated for by the 
fact that the mounting is far more rugged compared to a female SMA 
connecter.
commercial radios, and some of the newer commercial/ham radios from china 
use a male SMA on the radio, and this reduces allot of the above mentioned 
problems inherent with an SMA connecter.
If the antenna snaps off, you can easily replace the antenna instead of 
having to send the radioin for repares.
Whereas the tradditional radio female connecter will snap off with the 
antenna in most cases and requires costly repares.

All that said, personal experience is what you have and if your satisfied 
with your own observations, then that is good.

but just try to remember this the next time someone posts to the list about 
another sma snapping off the radio when it is dropped or impacted.
In 6 years of being on this particular hams list, I've never heard of that 
happening to a BNC connecter on an HT.
