I don’t have one specific as my favorite anymore and currently use Konsole from KDE. If you like tinkering with files and want it highly customizable through configuration files instead a gui, then probably Kitty is the best (and the closest to being my favorite). Alacritty is also a good one, but its quite simple and lacks some features in my opinion. I didn’t try too many, but these 3 are the top three I would consider using in the feature future.
