IPhone SE or iPhone 6/s/plus?

I'll be starting high school ~9th grade~ in about a month and I feel like I'll be needing some sort of phone eventually. I currently have an iPod touch 6. I've never really had my own iPhone or really a phone accept a few years ago when I had a galaxy S3 (which I no longer use because of bad battery life). The SE seems appropriate at the time being because I'm only looking for a device that's up to date and is not too pricey. I'm pretty sure I won't be making a lot of calls but it'll be useful for emergencies. I'll be mainly using it for taking pictures, going on social medias, texting, etc. So would the iPhone SE be worth it?

Spec wise the iPhone SE is almost identical to the 6s minus a few things such as the 3D Touch Display, 2nd generation touch ID and obviously it's smaller.

When it comes to performance, there isn't really a difference. It mainly comes down to what size phone you want
