xterm vs Konsole

Xterm is a very lightweight terminal. It requires few resources, allowing it to run well even on lower-end machines.

If you master xterm, you won't have to learn another tty, since it is in almost every Linux distribution.

Xterm is installed as standard software with the X Window system, and is there even when installing other terminal emulators.

Many terminal emulators that deal with wider fallback fonts (i.e. double-wide characters in CJK fonts) truncate display of wide characters, show Unicode "missing glyph" characters, or simply fail to display the characters at all. XTerm is "smart" enough to simply take up the extra space needed to show such wide characters.

See this.

Many terminal applications, such as OS X's Terminal.app and iTerm2 (among others), all claim xterm or xterm- variants as their $TERM and aim for support of xterm's escape sequences. Many command-line applications will assume or even hard-code escape-sequences and behavior for xterm and those terminals emulating it.

X Toolkit resources and xrdb predates what is currently called "theme". Although one needs to read man, mitigates most listed cons

Konsole can bookmark ssh and telnet sessions, directories, and it can open tabs in a folder for easy access.

Konsole supports split-view which splits the window into two (or more) konsole instances. This is very useful for people who work a lot on the terminal and don't want to spend time navigating between different windows or tabs.

Konsole supports true color and smooth font. This made konsole more fanstatic than other terminal emulators.

Konsole can be embedded into desktop so it's always easily accessible, but not in the way of other windows.

By going to file > save output, you can send all screen output to a text file.

Konsole can be accessed by pressing F4 in Dolphin, which is convenient for when the user needs to open the terminal in a particular spot of the file structure.

Most terminals in Linux don't support font ligature, while many modern fonts such as PragmataPro or Fira Code already have decent coverage of font ligature. Support for font ligature makes user experience and font management much easier (i.e. you don't need to keep two copies of the same font just to use in the console)

Users can associate each bookmark or SSH session with a custom icon, thus giving a visual hint to quickly identify a tab when a lot of tabs are open.

In particular solarized.

Konsole can monitor activities and notify the user through system notifications when a certain activity happens. This is a very customizable feature too: you can write scripts that can use this feature and notify you for whatever you want.

Konsole 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.

Profiles containing different settings can be created, saved, and loaded. Color schemes, window transparency, scroll bar, key bindings, start-up commands, window border, and menu bar can all be customized according to the user's needs.

Good menu to customize.
