Class Rank

Hi, my school is a non-ranking school however we do have the option to use report our class rank to colleges. I’m applying for many in state colleges Texas, like Texas A&M and UT. I am in the top 15% (100 out of 659). Some suggest not to report your class rank if you are not in the top 10, you will have a higher chance of getting in because college will rank you themselves. However, since our school is one of the most competitive school in the state, some suggest that top 15 will look good because they know the school’s competitive profile.
I’m wondering on what are your opinions on this.
