The most (and i'd say only) useful aspect of content_tag is the ability
to iterate over a collection:

<%= content_tag_for(:tr, @people) do |person| %>
<td><%= person.first_name %></td>
<td><%= person.last_name %></td>
<% end %>

which produces items with a predictable id and class.

<tr id="person_123" class="person">...</tr>
<tr id="person_124" class="person">...</tr>

see doc:
http://api.rubyonrails.org/classes/ActionView/Helpers/RecordTagHelper.html#method-i-content_tag_for

But in most cases where you just need standard tags, you should plain
ol' html because it's much easier to maintain.

<h1><%= @person.name %></h1>

is better than

<%= content_tag :h1, @person.name %>
