Should I go to a magnet high school, as a new kid or...

...Go to the school I have been going to since I was in kindergarten?

All of the girls I have/had interest in are going to the high school in which I attended my whole life, so what would work out socially wise? The new school, or the old school?

Even though I have gone to this school for so long, I am not popular, and I'm not lesser known. I would like to hang out with more girls and guys (majority girls). Your advice is really helpful.
