I've read that yes indeed, DWs can have problems. But I've concluded they can all have trouble. I have a Wilson that has not been right from the beginning (failure to feed, even with their recommended ammo) that needs to go back.
I like in the comparo linked to above the guy talks about how DWs are made -- low numbers, hand fitted -- but after close-tolerance machine work -- American parts, no MIM, etc. I think they can all have problems, but it's a numbers game and question of how good the quality, reliability, and accuracy, will be when you get one that is right. I suspect many sales DW loses to the TRP are primarily due to lack of availability of DWs and people can't see them in person before buying and, sadly, the tacticool factor.
The DWs give you more of the high-end for less money and have a higher likelihood, IMO, to be good to go from the get go. I suspect there's a reason you read so many stories on forums about Springfield's fantastic customer service -- people have needed it.
And none of this should be read as putting down other guns. I'm just saying you get a lot for the money with DW, but that wouldn't, and hasn't, stopped me from buying guns I wanted, even though I don't perceive them as being the good values I find DWs (I'm thinking of my two Ed Browns).
I'm all for buying all the variety of guns you can afford, that float your boat, and you're willing to learn the manual of arms for. Glocks, advocated above, don't float my boat. But I own three. Because I can't deny that they are what they are and they've earned their reputation. I own three HKs. Some randoms. And a crap load of revolvers including three or four Pythons. All of these things seem to go bang when I pull the trigger and allow me to hit the target satisfactorily enough for self defence work. But my nightstand gun is Sig P226 with a classic DA/SA action, even though I'm not much more passionate about them than I am Glocks. Why? It's the gun my wife can shoot well and readily operate all the controls of and easily clear if jammed. It's also close enough to her nightstand gun (P220 (her choice, by the way; she shoots it lights out and the single stack grips allow her a comfortable and secure hold and the slow push of a .45 is more pleasant for her than the pop of a .40)) that she can transition in a crises.
Ultimately, I'm sure there's no right answer -- though possibly some wrong ones
-- and people tend to favour what they're familiar with, what they already own, what they use at work, what floats their boat, what works for them, what fits their perceived priorities, etc. And few people ever want to admit they spent a lot of money wining and dining the fat, ugly, stupid, chick.
