quoting 10 reasons why jquery is better than mootools. source: http://www.jquery4u.com/articles/jquery-mootools/
jQuery has better mobile support than Mootools – the latest release of jQuery Mobile Alpha 3 has been a breakthrough in how easy it can be to get your website “mobile efficient”. Mootools has mobile support including touch events but it’s not as widely available as jQuery options. (#1 was Previously jQuery vs Mootools filesizes).
not true. see http://moobilejs.com/
jQuery is less confusing than Mootools! – It has less native extensions (including element) – jQuery has about a dozen for Array, Object, and String and Mootools has about six dozen for Array, Object, String, Function, and Number.
how is less power and methods a good thing? the reason why mootools has more native methods is because it also shims browsers that lack ES5 functionality for all the natives that it extends. if anything, this goes against jquery.
