Manjaro w/ KDE was my daily driver OS for several years before I switched to EndeavourOS w/ KDE a few months ago. The only major difference between the two that makes EndeavourOS more "terminal centric" is that you have to use the CLIs pacman and yay for installing packages, as Pamac the GUI package manager is something Manjaro provides. That said, I highly recommend making the switch and think with some small adjustments, you'll feel right at home.
