Question Ranking
Pros
Pro Low memory usage
Rxvt-unicode uses very little memory and takes a lightweight approach without losing many important functionalities. A single instance of urxvt takes about 6.5MB-8MB of RAM.
Pro Can be daemonized to reduce resource usage
For those who want to lower their system's resource usage, rxvt-unicode allows for daemonization. This way you can run several instances of urxvt inside a single process.
Pro Supports terminal transparency
Changing the transparency of the terminal is allowed for in rxvt-unicode. This not only makes for eye candy but is also good for GUI usability.
Pro Minimum dependencies and simple text config
Pro Supports multiple font types
Multiple font types can be displayed flawlessly in rxvt-unicode.
Pro Handles bold text colour properly
Displays characters with text attribute bold actually as bold glyphs.
Pro High performance
Rxvt-unicode is much faster than most alternatives.
Pro Unicode support
International language support is provided through Unicode.
Pro Proper wrapping support
During selection and pasting wrapped text doesn't break into lines at place of wrapping.
Pro Fast text rendering
Rxvt-unicode has very fast text rendering, being able to render hundreds of MB of text in a very short time.
Pro Built-in Perl interpreter
It has a built-in Perl interpreter, meaning that no install is needed. Simply run urxvtperl.
Pro End process notifications
When a process has ended, Pantheon Terminal sends a notification bubble to the desktop notification server and indicates which tab generated the notification.
Pro Can easily restore a previous session
Pantheon Terminal remembers the window size, position, windowed/maximized/fullscreen state, and open tabs in between sessions.
Pro Advanced tab handling
Using the Granite Dynamic Notebook widget (which includes tab close history), double click the tab bar for a new tab, duplicating tabs, quickly closing all other tabs, auto-hiding/revealing tab close buttons, etc.
Pro Smart copy and paste
The keyboard shortcut for copy + paste is intelligently adapted andnbased on text selection and clipboard state. This makes it possible to use standard copy + paste shortcuts without colliding with standard ctrl + c behavior in the Terminal.
Pro Search feature
Cons
Con Unicode characters that are too wide are blanked instead of clipped
If a character in a backup font is wider than the base font, urxvt substitutes the non-displayable character. A large letter space will show the wide characters, but the result is not reasonably spaced. There is a patch from 2014 that the urxvt maintainer will not merge.
Con Requires work to look acceptable
Out of the box, rxvt-unicode is not too pleasant to look at. Some understanding of Xresources is required for updating its appearance. That being said, the experience of customizing it can be very rewarding.
Con Requires work to configure useful functionality (clickable URL's, font scaling, tabs)
Con In daemon mode you can lose all your terminals
Because of sharing the same process terminal windows cannot be killed without sacrificing all other open windows. That becomes even more dangerous if you use multiple graphical managers without overriding socket with RXVT_SOCKET.
Con Unicode rendering is buggy
There are a few references to urxvt's buggy rendering, such as unicode combining characters, which bled through during scrolling.
Con Bloated
Exists because Xterm is complete trash. Although it has a lot of features, you will most likely never use them all.
Con No support yet for 24-bit "True Color"
Though this is still not available, you can download the patched version for 24bit, here.
Con Font size cannot be changed on the fly with the mousewheel
Sometimes you may need to enlarge the font to improve readability, or shrink it to have more real estate and "hawk's eye" view of data. In rxvt you need to change the configuration file or use these commands:
$ function fontsize
{printf '\33]50;%s%d\007' "xft:Dejavu Sans Mono:size=$1::antialias=false"}
$ fontsize 22
Con No option to have a "reverse color" cursor
While you can choose the color of the cursor and the character under the cursor, there's no automatic "reverse color" for the cursor. This makes it impossible to use rxvt-unicode if you have a light background terminal and a dark background editor.
Con Heavy
Con limited customization options
Con RAM usage increases considerably over time
There is a RAM leak when using the Pantheon Terminal that adds up over time and use.
Con Incompatible with LTS Ubuntu
Pantheon is developed and binaries are released for a near blessing edge operating system (elementary OS). As such, installing it on an LTS Ubuntu system may be nearly impossible without replacing a large portion of the LTS stack that Ubuntu-targeted software expects.
Con Restrictive license
