Termite is a minimalistic terminal emulator. It does not need too many resources to run and it's designed primarily to work with window managers.

Cons
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 No support yet for 24-bit "True Color"
Though this is still not available, you can download the patched version for 24bit, here.
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 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 Requires work to configure useful functionality (clickable URL's, font scaling, tabs)
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 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 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 Difficult to install in some distros
Con Can't change keybinding
Con Cannot set specific parameters through CLI arguments
Setting specific parameters through CLI arguments is not supported in Termite.
Con Limited documentation
There's only short manpages and a README on the front page of the repository which has few details on additional configuration and features.
Con Bad URL matching
Per default, there are some inconvenient issues with url matching.
Con Problem correctly displaying images while using compton
Images can sometimes not be displayed correctly in software such as ranger while using compton.
Con Slow text rendering
