[Android Central Question]

I know this is going to sound incredibly shallow, but I hate the new emoji designs. I'm pressing "no, maybe later" at the prompts that keep showing up telling my to upgrade but I don't want to keep doing that forever. Is there a way to make the prompt stop showing up? Or a way to upgrade but go back to the old emoji look?

For that matter, is there a good reason to use Oreo that would actually affect the way I use the OS? My phone works fine for me as is, but I could be convinced to update if there was some huge improvement I was missing.
