There are a lot of Behringer haters out there, that's for sure. They make budget equipment and one shouldn't expect a Hyundai to perform like a Ferrari. Value is in the eye of the beholder; their gear fills a niche and does OK for what it is. Their EQ's may be a bit noisier and less frequency selective than their more pricey brethren, but a Behringer EQ isn't likely to fail catastrophically and send your system into roaring feedback or anything. If I were building a multimillion dollar studio for top tier recording I wouldn't have any of their gear, but for playing the bars on a limited budget... meh.
People used to say the same thing about Peavey gear; maybe they still do. I have a couple of 30+ year old CS-800's in my rehearsal space and they are still going strong. They are loud and they are bulletproof. So they hum a little bit and they weigh a ton. So what? I paid $250 for the pair of them and they do exactly what I need them to do.
