Which phone choice is best?

I'm 14. I'm trying to buy my own phone by myself, since my current phone's software is failing. I don't want to burden my parents, so I went and got a temporary job to get money. The four choices are: iPhone 5s ($244) iPhone 6 ($524) Samsung Galaxy S6 ($584) or Samsung Galaxy S6 Edge Plus ($499). I current have the ZTE ZMAX 2 with 5.5" screen. I'm leaning towards the iPhone 5s even though it is much smaller. Contracts are not an option. My parents are also very cheap, and even though im paying 100% they aren't happy at the though of $500 , and don't really like $250 but will accept it. Thoughts and advice?
