Is it considered more professional to write a website in strict rather than transitionl html?

Question

I was wondering if it was considered more professional to write a website in strict xhtml rather than transitional.

Is it something that should be done as you advance as a web developer, or is it irrelevant?

With the possible exception of the (rarely needed) start attribute, the difference between Strict and Transitional boils down to "Things you should not have used since Netscape 4 stopped being a dominant browser".
