Chasing Rails

At the risk of adding to the echo chamber, I’d like to point out the React Framework for Zope, a Zope 2.x product which attempts to ease web development by “stealing ideas from “Ruby on Rails”:http://rubyonrails.org”. OK, so this looks cool. But I can’t help wondering why Rails has become the gold standard that web application frameworks aspire towards? Between React, “Subway”:http://subway.python-hosting.com/ and “CherryPy”:http://cherrypy.org (which Subway uses), there seems to be quite a bit of interest in coming up with either “Python on Rails” or a “Rails Killer”. Is Rails really that good? I admit it looks cool, but I haven’t actually used it. Can someone help me out on this?
