qTip: awesome tooltips with jQuery

I honestly can't say this is the best tooltip plugin for jQuery because I haven't tried out very many of them. But I did read through the jQuery plugin repository descriptions pretty thoroughly and tried out a bunch of demos.

And I landed on qTip   http://craigsworks.com/projects/qtip/

I can say that qTip is awesome. It is versatile and easy to use. It has many render and behavior options, for example, for making professional looking bubble tips. The online documentation is excellent.

Some notable notes:

• While there's generous styling options built-in, you can gain complete css control too http://craigsworks.com/projects/qtip/forum/topic/475/complete-control-via-stylesheet/
  
• Someone's worked out how to make the styles Themeroller-compatible. I havent tried it yet but looks promising. http://craigsworks.com/projects/qtip/forum/topic/211/qtips-with-jquery-ui-css-and-themeroller/
• The author promises a new corners engine, which will be smaller and allow 1px border widths
• It can be used to replace normal html tooltips (title), inline tips (content can be even be stored in DOM data attributes), AJAX content (which i havent used), form field help (e.g. with onfocus events, which i plan to use),
  
• and more.
