Linux

Kitty and Konsole

I like Konsole.

It comes with KDE, supports tabs, themes, and loads very fast.

I don't really need more from a terminal than that. When I, rarely, need more advanced features like window splitting and session management I also use Zellij (previously I used tmux).

I like Tilix, since it lets me split the terminal with a keyboard shortcut and easily switch between terminals too. I tried using GNOME terminal + tmux, but having to hit Ctrl+b before the command I wanted got tedious fast.

Bengaluru's Kempegowda International Airport's Terminal 2.

VT2. Sometimes 3.

I really like kitty. It is fast and simple but gives me all the features I would want.

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.

I like Terminator,
for it's ability to split one terminal window into as much as you want:
https://gnome-terminator.org/

In combination with Fish shell,
for it's auto completion + syntax highlighting:
https://fishshell.com/

And lastly, BobTheFish,
a nice git-aware powerline theme to go along with it:

I'm on the Alacritty/Tmux/ZSH train. Haven't any issues, other than font scaling differences between laptop and desktop UW monitor.

I use blackbox, looks nice and can customize shortcuts. https://itsfoss.com/blackbox-terminal/

Favorite terminal? iTerm2 on mac, hands-down. Wish they would port it to Linux.

On Linux though, I usually end up using guake, as I like having easy drop-down global access to my terminal.

I use Hyper because it’s pretty simple to setup the way you want it and carry the config across OSs.

Tilda, because I can bring it down my screen with one key any time.

I use kitty, specifically because of the icat kitten (that draws images on the terminal) and its integration with the lf file manager's preview.

Wezterm is my favourite because it's really configurable and supports ligatures. Konsole is also quite nice. Generally I'm in favour of using whichever one comes with your DE, or Wezterm if you use a WM.

Kitty is probably the most popular one, but I don't like it cause ~~no ligature support~~ ~~no acceleration~~ it claims it has good font management, but fonts never worked properly in my experience.

Alacritty and Foot are also popular for their performance. Alacritty does have some stability issues though.

I use ddterm. It's a gnome extension that adds a Drop Down Terminal. I quite like how easy it is to bring it up and hide it again, at the press of a button. You can even hide it without closing it, so it's great for testing web apps.

My favorite is Alacritty but I don't use it because of stability issues lol. Kitty is popular now. It seems to have some questionable update policy but it's fixable. It supports plugins (kittens), tabs and most of the common features. Though the configuration is done in a text file. It doesn't have a GUI for it. For that I'd recommend Konsole

None, they all have pros & cons.
The most popular in the Linux space is probably Alacritty & Kitty.
