My biggest reason for using it over gnome terminal is osc52 support
https://ali.anari.io/posts/osc52/ which lets you copy paste using a escape sequence. Meaning you can copy paste when ssh'ed into another machine. Gnome terminal doesn't support this currently and there is a discussion on whether they will because of security concerns
