You wont be making a bad choice by going any of the brands your picking but when push comes to shove and you need parts, is where having a piston gun would suck.
In the case of the Barrett, that gets down to the bolt + carrier, the piston system (2 parts), and I guess you'd have to add in the gas plug. So, then the real question becomes, how often do you expect to replace those parts? I'm not sure there's an answer to that yet. I would expect the bolt + carrier to last as long as a DI, the piston system (unknown), and the gas plug (unknown).
Since the gas plug is a non-moving part, and really not subject to wear, I'd expect the worst thing that could happen is that you'd lose it. Not sure how, but nothing's 100% so there's always a chance some how some way.
Then it gets to the piston system. That truly is unknown, but knowing the materials and coatings on it, I'd expect as long or longer than the bolt+carrier. I suppose if you're that worried about it, you could buy a bolt + carrier, piston system, and gas plug when you bought the rifle and be ready for any eventuality. I'm not one to do that, so I just continue to use my REC 7 without spare parts. I'll see what happens in the next 10 years with it.
Personally, DI or piston? I don't care either way. I own one of both styles and have my own thoughts on it, but it doesn't get into to advocating one as being better than the other - they're only different.
