guake-terminal for a full-screen overlay terminal, I have a keybinding for transparency toggle so I can read guides through the overlay. I used to use tilda, but I switched because they weren’t supporting wayland.
For random/ad-hoc terminals I’ve historically used gnome-terminal and console, but recently I’ve been trying to eliminate window decoration entirely, and for that I’ve been liking black box (flatpak) for the floating decoration and other configuration bits.
They both support theming, and have dracula included by default, so it was easy enough to get a consistent look and feel.
I have tabs switched off for all of them. That’s what tmux is for.
edit: I’ll probably be checking out alacritty
