Hey guys. I use the build in terminal of linux and im really confident with it, but i believe there have to be better out there. Any suggestion?

The terminal emulator is not "built in" but traditionally comes bundled with the distribution or DE that you've installed. However, you're free to install any other terminal of your choice. As far as I'm concerned, "terminator" is a popular choice among advanced users.

I'm fond of terminator due to its split screen feature.

Definitely Terminator for me.
