Ranked in these QuestionsQuestion Ranking
Pro Exceptionally fast
The Gnome Terminal is usually very fast. It boots up very quickly and takes less than a second (averages to 0.25-0.59 seconds) to display files of up to 600 MB.
Pro Content re-flow when window is resized
When using the GNOME Terminal, if you have long lines of text inside it and then you change the window, the text will also automatically update according to the new window size.
Pro Support for tabs
Gnome Terminal allows for the use of tabs by right clicking in the terminal window and selecting open new tab or by pressing
Ctrl+Shift+t by default.
Pro Supports scrolling
You can scroll up and down in Gnome terminal. And if you wish to do so, you can also hide the scrollbar.
Pro Clever memory management
Multiple terminals are managed from one gnome-terminal instance that takes up about 45 MB. Adding on other instances (with 10k lines of used buffer), each terminal requires about 16 MB of memory.
Pro Good integration with other GNOME-Shell apps
Gnome Terminal integrates well into Gnome Desktop, as well as the rest of the core Gnome Shell apps.
Pro Configurable keybindings
Configurable keybindings can be used for copy-paste, sending sigint, switching tabs, and so on.
Pro Solarized colors
Gnome Terminal comes with a solarized colorscheme installed and ready to use.
Pro Drop-down support
Drop-down functionality can be added to Gnome Terminal via an extension.
Pro Notifications upon command completion
This isn't in the current release but in development versions you get notifications when commands are complete. This is great for long-running commands, relieving you from continuously checking to see if your command is done.
To achieve a large amount of speed, Gnome Terminal has to use a relatively large amount of memory to run. It may eat up to 15-30 MB per instance, depending on the task it's doing.
Con Gnome library dependencies
While not an issue if using Gnome, when trying to use this terminal in other desktop environments or window managers there will be a large amount of dependencies tied to the app making for a large install size. For those trying to keep their desktop lean this may be an issue.
Con No tab names
Since Gnome 3, the feature for manual renaming of tabs was reaped off.
Con No background transparency
While this used to be an option, background transparency has been removed.
