I’ll be real with you, it’s just familiarity. Whenever I’m setting up a new system, I just install Guake and throw my config file at it, so it feels the same as all of my other computers.
I’m sure that Yakuake is great and that all drop-down terminals probably have identical feature sets. However, I’m getting too old and impatient to distro/software hop. I just like my stuff to work and as long as it does, I don’t change it.
Concerning DE compatibility though: I run cinnamon on most of my machines and Guake has worked flawlessly for me for years on Cinnamon and Gnome. I’ve never been a fan of KDE though, so your milage may vary.






Debian with cinnamon.
