8 - Meta tags, which is better?

I have two pieces of code from different sources tha are supposed to be good for seo:

1 -

<title><data:blog.pageTitle/></title><LINK REV="made" href="mailto:rincon.rise@gmail.com"&gt;<meta content=’The exploration of Kaizen. The strategy for continuous improvement in life and business’ name=’description’/><meta content=”kaizen, improvement,self-help,business, life′ name=’keywords’/><meta content name="author" CONTENT="Javier Rincon"><meta content=’INDEX, FOLLOW’ name=’robots’> </meta>

I can't remember the source of this.


2 - To replace this:

<title><data:blog.pageTitle/></title>

With:

<!-- Start Widget-based: Changing the Blogger Title Tag --><b:if cond='data:blog.pageType == "item"'><b:section id='titleTag'><b:widget id='Blog2' locked='false' title='Blog Posts' type='Blog'><b:includable id='comments' var='post'/><b:includable id='postQuickEdit' var='post'/><b:includable id='main' var='top'><title><b:loop values='data:posts' var='post'><b:include data='post' name='post'/></b:loop> ~ <data:blog.title/></title></b:includable><b:includable id='backlinkDeleteIcon' var='backlink'/><b:includable id='feedLinksBody' var='links'/><b:includable id='backlinks' var='post'/><b:includable id='status-message'/><b:includable id='feedLinks'/><b:includable id='nextprev'/><b:includable id='commentDeleteIcon' var='comment'/><b:includable id='post' var='post'><data:post.title/></b:includable></b:widget></b:section><b:else/><title><data:blog.pageTitle/></title></b:if><!-- End Widget-based: Changing the Blogger Title Tag -->

Are these bits of code exclusive, which one works better? What are the actual visual and hidden results behind them?
