For me, reading isNotEqual() introduces an extra mental variable. I have to spend extra effort to keep track of the bar over the statement that doesn't exist in the text. But that said, I see no reason that someone couldn't learn to parse notX as fluently as I parse !X. I suppose it's one of those fashions that change with the times. Probably a big reason that I stick to good old C a lot of the time.
