9term is what I use the most. Once you get used to the Plan9 way, you kind of like it. Sometimes I use Terminator as well. Konsole is like Terminator, both are good. They are both nicer than kitty for me. I tried kitty, went back to Terminator as it has menus to edit things, not just a text file.
I like just good old gnome terminal. Theming scripts work well with it, like the gruvbox one that has like a hundred color themes. it's got all the right features. just works
Try out warp. They have built in Ai help, and a lot of features. The Linux version is available since 2 weeks.
Cons: you need to create an account https://app.warp.dev/
Guake. Has been for years. I am in and out the terminal all the time, so F12 works well for me. Plus I used to play Quake and used the in game terminal to do all kinds of things. Plus I'm an old RISC OS kid and F12 was the key to get the "star line".
