what are the differences between adding a link to a publishing page using; [[PageName]] & insert link from address & insert link from sharepoint

Question

I am working on an enterprise wiki site collection inside SharePoint server 2013. now I want to add a link to another wiki page inside the same site collection, but I find that there are 3 main ways of doing so as follow:-

1. using the [[ ]] appraoch
2. edit the wiki page >> Insert >> Link >> from address >> type the full url of the destination page such as http://servername/sites/siteA/Pages/Page1.aspx
3. edit the wiki page >> Insert >> Link >> from sharepoint >> type the full url of the destination page such as http://servername/sites/siteA/Pages/Page1.aspx

now for me, the three approaches will do the following:-

1. they will automatically update their URL in case I change the URL for the destination page. so if i change the URL for the destination page from page1.aspx to page2.aspx then the 3 links will automatically update their URL to match page2.aspx.

now when I edit my wiki page which contains the above 3 links, and I view the Page source (in edit mode) I got the following:-

<p>[[page2|page1]]</p>
<p>
   <a href="/sites/siteA/Pages/page2.aspx">test</a></p>
<p>
   <a href="/sites/siteA/Pages/page2.aspx">test</a></p>
<p>&#160;</p>

also when I am in the view mode, I checked the generated markup for the 3 links and I got the following:-

<p><a class="ms-wikilink" id="0::page2|page1" href="/sites/siteA/Pages/page2.aspx">test</a></p>
<p><a href="/sites/siteA/Pages/page2.aspx">test</a></p>
<p><a href="/sites/siteA/Pages/page2.aspx">test</a></p>

so now I am totally confused if we need to communicate which approach our end-users should follow to link different wiki pages? or at the end the 3 approaches will have the same result, and it is a matter of preferences ??

Thanks

Well, if you have Wikis, I suggest stick to the Wiki format with the square brackets - I mean, after all - it is Wiki, right? :) Plus, you'll get updated title of the target page, when it changes, not just the URL.

Other two options exists, because they are basic features of SharePoint and are used in all kind of sites (team/publishing).
