Slim 3 Is the Way

 So yeah, I'm going to switch to Slim 3. My 100% scientific reasons? 

1. It seems to be structured very similarly to Silex.
2. It's compatible with the version of PHP I'm currently using (PHP 7.4.11).
3. It appears to be quite lightweight (no benchmarks or whatnot to prove that as of yet).
4. I can install it via composer without any of the problems I was experiencing with Symfony/Flex
5. It is (according to Laravel) faster than Silex.
6. It uses Pimple as a dependency injection container and I loves me some DI.
