Here is my $.02 on the X vs DL argument. I own a DL1608 and have mixed quite a few shows on the X32 Compact and full size X32.
Like others have commented I have not heard of any widespread X32 issues. Behringer made a significant investment in R&D and manufacturing upgrades to produce the X32 series. It is NOT the 'old' Behringer QC that used to be the brunt of so many jokes. I have heard of a few issues, an occasional post about a console rebooting during a show, obviously not good, but I've never heard of one outright dying and it's certainly never happened to me.
I like my 1608, it's a good mixer, however, I dislike the effects, they sound cheap, the inline power supply, primarily the coaxial power plug, is a weak point and I really dislike the lack of recallable preamps, switchable phantom power on individual channels, and if you have a low gain mic that requires a high gain setting you can hear the LED's clicking as they flicker with audio. I also hate not having selectable pre/post aux settings on each channel instead of the whole bus (MF 3.0 fix??)
I am looking for a step up from my DL1608 for bigger shows. When I look at the DL32R I see virtually nothing in it that makes it a superior mixer to the X32 series, even the X32 rack. As has been pointed out for basically $100 more than the DL32R you can have an X32 Rack with an S16 add-on or buy a pair of X32's for just a hair more and have two for smaller shows and ganged together for 32 inputs on a big show.
The effects on the X32 are so much better than the DL series it's not funny and there are a lot more available. The routing is vastly superior, including send options, you have numerous RTA options, you have many more DCA's and subgroups, you have PC control and management capability via network, not just USB, and the USB to drive feature really isn't that big of a thing for me.
Plus you have control surface options. Last year I mixed 12 bands in two nights for a large festival. I could have mixed on my iPad using my 1608 but when you get wild and crazy band/set changes the iPad is just too restrictive, I want faders, buttons, and switches that I can grab quickly and easily. I still used my iPad on stage to set monitor mixes but I had a full FOH setup for when the band was performing because I need to make adjustments much more quickly than I could via an iPad constantly swiping around.
Something I forgot to credit Mackie with, I do think their iPad UI is one of the better ones out there, easy to navigate, when I do use an X series mixer I miss the ability to swipe left-right compared to using blocks of channels
