<p>I compared many universities between QS world university ranking and times higher education ranking. Some universities like Strathclyde university Glasgow which have given 5 stars in QS world university ranking does not even exist in Times Higher Education world university ranking and same for Dublin city university, Ireland.
Also some universities which have given good ranking by Times Higher Education (at lower level) are not in it he QS world university ranking.
I am confused between two 
. Which ranking is better QS or THE ?</p>
<p>All explained in the methodology section of each ranking.</p>

<p>To be honest, neither of them are useful if you want to decide where to apply for your Bachelor’s degree. That’s because both rankings emphasize the research productivity of universities, measured in various different ways (publications, citations, reputation surveys, research funding, etc). Undergraduate students care about other factors:</p>
<ul>
<li>The quality of teaching.</li>
<li>The employability of the university’s graduates.</li>
<li>Their general quality of life. (Location, food, housing, etc.)</li>
<li>Affordability.</li>
</ul>
