To me, the big advantage of pistons was they didn't bake off the bolt group lube.
The new FailZero coatings mitigate this issue away to a great degree with none of the baggage the pistons induce.

My brother saw Deliverance and bought a Bow. I saw Deliverance and bought an AR-15.
Far from it. I'm very good at breaking shit left and right. This is why my new Limited gun for USPSA is a S&W M&P40 5" Pro. I got tired of dumping $100s of dollars keep my STI running.
Back to the AR. I break shit and wear shit out on DI guns on a regular basis the difference is I can get parts from Brownells, BCM, LMT, Colt, Daniel Defense, and many others and know it'll work. If I bend an op rod for piston gun it's only available from the original manufacturer same for any other proprietary parts associated with them. Also I know how to keep a DI gun running and know how to properly assemble one.

What Happened to the American dream? It came true. You're looking at it.

HK416?
Allow me to chime in on that. When I was in A'stan recently (last 90 days) I was at a location where a certain Army unit that was using the 416 was located.
I spoke to some of those individuals and asked what they thought about them. All the comments were pretty positive. When I asked about maintenance, parts breakage, etc... non of them could tell me if anything was replaced.
I was told that when the return to Ft. Bragg, they get inspected and who knows what else.
I don't think that any of us are saying the 416 is bad. But, it's also not the wunderwaffe that it was touted to be. I also think that for their purposes they are probably just great. I also think that if stuff was breaking you definitely wouldn't hear them talking about it. It would more than likely come from outside sources.

My friend is in unit that is oldest and most hard-use user of HK416 here. He personally is issued KAC (old version SR-16) and loves it. But guys from "front-line" use 416 and has nothing bad to say about them. They do carry them back to unit armourer but mostly to let him clean it for them or make scheduled maintenance. My friends do not remember any info on failures and problems.
They switched to 416 from SR-16 mostly because they had problem getting parts for SR-16 and found out that 416 is gives them some more margin. Before decision was made they had some samples for some time that got beaten and eventually they managed to push them to failure point. Every man made thing have failure point - it's important to know where it is.

You can't really judge the quality of something because an Army 'Unit' uses it. Hell not to long ago they were using STI .40s and then Glock 22s.....

Everything is going to break and fail at some point. They are tools. In fact, one person mentioned that if you don't run something till at least one part of it breaks, you're probably not running it hard enough. I hate it when some people find one or two guns breaking out of a whole batch after the guns have all been shot like 20,000 rounds, been abused, and went to war, and then say that the system is unreliable or a piece of crap.
That being said, I think that the pro-DI people are saying that the availability of parts of a DI gun and lack of extra weight make it a better system. They are saying that the piston guns also suffer from a few parts breakage problems and some suffer from carrier tilt. Pro piston people usually claim that the system runs cleaner in the bolt carrier area and that the guns need less maintenance in general. I think it'd be safe to say that both systems (if set up properly) have their merits.
I agree, and get a little tired of the "look who uses what you're poopooing" argument. My needs, budget, support, application, training, etc. are not that of a military unit. While what one uses or doesn't use, failures or successes reported, and other information may be of some value in the overall analysis, in and of itself it means little to nothing.
