Transitional is Strict plus a big pile of presentational junk that we left over from the browser wars of the late 90s.
The idea what that Transitional could be used while people transitional from HTML 3.2, there should be no need to use it today as browsers have caught up.
Transitional doc type allows you to use very loose and deprecated coding while your pages are in transition to better coding. In general, most of the differences between using a Transitional and a Strict DOCTYPE have to do with the guideline that with a Strict DOCTYPE, all presentation information should be in CSS, not in the XHTML markup.
HTML 4.01 Strict does not allow presentational markup with the argument that Cascading Style Sheets should be used for that instead
XHTML is a family of current and future document types and modules that reproduce, subset, and extend HTML 4 [HTML4]. XHTML family document types are XML based, and ultimately are designed to work in conjunction with XML-based user agents. The details of this family and its evolution are discussed in more detail in [XHTMLMOD].
XHTML 1.0 (this specification) is the first document type in the XHTML family. It is a reformulation of the three HTML 4 document types as applications of XML 1.0 [XML]. It is intended to be used as a language for content that is both XML-conforming and, if some simple guidelines are followed, operates in HTML 4 conforming user agents. Developers who migrate their content to XHTML 1.0 will realize the following benefits:
* XHTML documents are XML conforming. As such, they are readily viewed, edited, and validated with standard XML tools.
* XHTML documents can be written to operate as well or better than they did before in existing HTML 4-conforming user agents as well as in new, XHTML 1.0 conforming user agents.
* XHTML documents can utilize applications (e.g. scripts and applets) that rely upon either the HTML Document Object Model or the XML Document Object Model [DOM].
* As the XHTML family evolves, documents conforming to XHTML 1.0 will be more likely to interoperate within and among various XHTML environments.
The XHTML family is the next step in the evolution of the Internet. By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content’s backward and future compatibility.

Strict is close to what HTML was intended to be.
