I've only used Mackie mixers and have never had a failure. Though, I did notice a big improvement in the noise floor and overall sound quality when going from an SR24-4 to a Tascam DM24, at our church. The Mackie was much "darker".
I have used lots of Behringer and have personally experienced a few failures. Once, I had a Composer Pro in front of an amp for peak limiting and when I powered up the amp rack at a show, the speakers were JAMMING some real nasty sound and I about sh_t me drawers. (yes the amp inputs were up) Well, figured out that the levels were maxed on one of the limiter channels, from internal demons
. That was one of a few, not so fun experiences. And, I've had friends have similar happenings.
Burn me once, ok, burn me again and again, ok, I get it.
I do still use some Beh gear (mdx4600's for channel compression and deq2496 for delay/rta), but I won't be buying more, at least anytime soon.
I am falling into that line of thinking now with Mackie, too. The shortcomings of the DL, hard and softwares, will probably erase it from the market. Getting fixes for the poor design has really been hard to swallow.
But, until it's replaced...
