Cons
Con Not cross-platform
Linux only, and additionally targeting GTK3.
Con Not very responsive
Occasionally, Guake slows down and is not very responsive.
Con No font ligature
Guake uses vte for its terminal emulation, and vte simply doesn't support font ligature (yes, it's 2019). This is what its maintainer thinks about it.
He really thinks supporting font ligature breaks terminal's grid, like he doesn't understand a font that's monospace is a monospace no matter if it has ligature or not.
Con Cannot set text color for character under cursor to background color
Suppose you have a dark background with a light cursor and light foreground color: the light cursor will cover up whatever character it is on, so that you cannot read it. There is no option to set the foreground color for the character under the cursor to what is normally the background color. Such an option would allow you to read the character under the cursor.
Con Execution in xfce4-terminal - e mode is not always functional
Con Resizing text resizes window
Con No profiles
There's no profiles or profile-based customization in Xfce-terminal.
Con Can't scroll on spamming text
When text generates too fast, you can't scroll it, so you just can't read anything in such moments.
