I think its a horses for coarses kind of thing.  You can get a lot of 
milage out of a good soldering iron and good technique.  Some things 
are easiest with paste/reflow though.  Ceramic smt caps spring to 
mind.  It's pretty easy to damage these with thermal shock.  A hot 
soldering iron can create hairline cracks on these and they can fail 
fairly quickly.  I use paste/reflow for these.  I still use an iron 
for most everything else.  It's pretty easy to drag solder tight 
pitch smts if you've got a good iron and lots of flux.
