Is it worth getting an iPhone if i have an iPod Touch?

I have a flip phone and an iPod Touch, i use the flip phone just for calling and i use my iPod Touch for the internet, facetime, imessaging, the camera, and everything else. I love it, i have the iPod Touch 6th Generation, i bought in 2017 and it was my first apple product. I was thinking about maybe buying an iPhone, should i get one if i already have an iPod? What's better about it?

The 1 iPhone would replace the 2 devices you have now.
