The good  quality N connector (the type with ground flange) is much more
reliable and  mounted with 25Wtts soldering iron in few minutes .

If you wish to spend the money, PL259 are available in pressure sleeve  type 
connectors similar to the better class N and BNC types. Used  these on our 
local VHF repeater duplexer which came as original equipment with  SO239/PL259. 
In the right place the SO239/PL259 combination is entirely adequate  up to VHF 
and most VHF 2 way radios seem to come so equipped. All of the GE  2 way VHF 
radios and repeaters we used at work certainly did. In addition a  great deal 
of the station accessories on the market come already equipped with  SO239 
sockets.
 
It would be wrong get the idea that just fitting N type connectors  will make 
you bullet proof as there are some extremely poor N and BNC connectors  on 
the market much as there are of the PL259 type.
 
The N type connector has a limited moisture barrier, though if the  connector 
has to be used outside in a damp climate, an external moisture  barrier tape 
over the entire connector assembly would be essential. Even so for  any 
connectors that have to be used outdoors, the N type connector would be  desirable.
 
In the end inside the shack for HF and where moisture should not normally  be 
a problem, it is a matter of using whatever connector you a comfortable with  
and want to adopt as a standard for your station.
