I have one of those, and for my purposes, it's more than adequate. I can understand that people appreciate something more sophisticated (literal meaning: "complex") but a well-constructed and maintained plain bearing (bush) can be just as smooth and robust as a ball or roller bearing for simple pivot duty, and is usually more forgiving of worn or imperfect seals in harsh environments. It's main drawback is its weight, but I've been thinking of taking mine to a friendly machine-shop to add lightness (as Colin Chapman put it).
