Questioning the worth of my 625 reminds me of the last person who questioned the worth of my Harley Davidson.  Hey, there are faster, lighter, and more reliable bikes out there so  why keep dropping $ into that heaver and slower Harley?  I'll politely relate to you the same kind of comment made to the rice burning jockey who was bashing my Harley:  If you don't already know why I go with a Harley and a 625 S&W it wouldn't do any good for me to try and explain it to you.
My 625 came good to go, I'm just tweaking it a little like I know from reading your stuff that you do too.  If we ever end up at the same range I'll offer you the opportunity to run some .45s through it and I'll bet your tone about 625s changes substantially.
