Why does everyone hate the desert eagles?

I know they aren't for everyone, but my brother just bought one in the 50 ae. It is a very nice gun. It is expensive, heavy, and a poor choice for self defense, but it seems to work perfectly for what he wanted. His has not had a jam yet, and most problems can be tied back to improper stance, or a bad mag. Any pistol can jam if it is limp wristed, it just happens more easily with a 50 ae because of the heavy springs. He bought the desert eagle because he wanted a big bore handgun for protection against bears when hiking and maybe even deer hunting, and he personally doesn't like revolvers. Me, I love my Super Redhawk 454 Casull, but I do have to admit that Desert Eagle is a very nice pistol. Not to mention it is much easier to shoot than my 454 Casull. It does not kick near as much as I had expected; it is much more pleasant than my 454. So why do people rag on those hand cannons. Like I said, they aren't for everyone, but they do have their place.
