Not really, is just that emacs is such a powerful programming environment that it's strange to see someone that knows it, leaving it, because the alternatives doesn't really offer much in return IMO.
I left Emacs for Sublime a few years ago, after almost 20 years of Emacs. Sublime isn't the greatest in feeling native to the platform, but it does better than Emacs. I prefer to spend my time on my projects instead of the editor itself.
