When saying &quot;the main bottom-line difference between X and Y is that Y is better&quot;, you&#x27;re implying that you&#x27;ll say something interesting and nuanced and then... not.<p>I could say &quot;the main difference between Ruby 1.8 and 1.9 is that programs run twice as fast in 1.9&quot; (true, 1.8 is dog-slow.) And that&#x27;s &quot;Y is better&quot;, but it&#x27;s also fairly specific.<p>&quot;Python 3.0 makes it easier to produce high-quality software&quot; is annoyingly vague. They seem to <i>mean</i> software that behaves more consistently by reducing the amount of default unpredictability in the language spec -- that&#x27;s fair and specific. It&#x27;s also not what the article said, sadly.
