<title>This is title element</title>
<meta name="title" content="This is title meta tag">
<a href="/some-url" title="This is title attribute">Some anchor text</a>
In my opinion you should only use the first entry in your list:
<title> ... </title>
That's all I ever use in my pages. I recommend that you delete the title meta tag and the title attribute since they aren'y needed for anything.
