it depends on what type of html document you are making... you can get more details at

normally for xhtml... your 3rd doctype should be used...

None of the above.  If you are serious about writing quality XHTML then you should use the STRICT XHTML DocType.  This will force better quality code as transitional code (a mixture of different versions) generally won't validate

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Which ever you choose, it is a personal preference. They will all display your content. There are reasons for using one over the other that depend on your project.  This chart may help.  http://www.zvon.org/xxl/xhtmlReference/Output/comparison.html.  Now you can use html5 which requires no declaration and that will be the trend.  

There will be good arguments for and against "strict" but this is what the top sites are using...
