Is there any difference between
<body dir="rtl">
and
<body style="direction:rtl">
?

<body dir="rtl"> is more appropriate as per W3C recommendation:
http://www.w3.org/International/questions/qa-bidi-css-markup
Because directionality is an integral part of the document structure, markup should be used to set the directionality for a document or chunk of information, or to identify places in the text where the Unicode bidirectional algorithm alone is insufficient to achieve desired directionality. [...] You should therefore use dedicated bidi markup whenever it is available. Do not simply attach CSS styling to a general element to achieve the effect.
User-agents that ignore CSS will also benefit from this approach.

I think this is a good answer, but a combination of both methods can give some styling power. For example you can (using CSS) float an element left or right depending on the class (.ltr or .rtl)

Once you have the html attribute, you don't need a class. You can use attribute selectors like
[dir=rtl], :not([dir])
