I’m pretty sure someone thought

Man it would be nice if horses were faster

I’d say the same is true for terminal emulators.

It would be neat if I could use tabs

Or

I wish there were better ways to render things to the terminal

At the end of the day it’s a black box where you can type commands. If thats all you need than you need anything else.

A terminal is a terminal. If there is a feature you don’t know you need then you don’t need it. Run with whatever you have

There is still a lot to learn from running arch before you try gentoo

Gentoo is basically arch but built around everything being compiled locally. There isn’t to my knowledge any “Gentoo-install”, but if you can manage to install arch manually it should be quite similar. Gentoo is a bit more complex than arch so if installing gentoo manually seems daunting I would recommend staying on arch.
