Ranked in these QuestionsQuestion Ranking
Pros
Pro Drag and drop
ROXTerm supports dragging and dropping items into the Terminal window.
Pro Advanced D-Bus usage
In ROXTerm, users can use D-Bus to configure terminals from other applications, allowing for communication between multiple computer programs.
Pro Includes a configuration manager
ROXTerm includes a configuration manager which can easily be run by selecting Configure...
in the terminal's menu, or by simply running roxterm-config
. You can then easily swap configuration files with other users, manage profiles, and customize things like color schemes or keyboard shortcuts.

Pro Supports GTK3
ROXTerm uses the latest GTK widget set which is great a multi-platform toolkit for creating graphical user interfaces.
Pro Scalable fonts
Font size in Terminology automatically scales according to window size. When you resize the window, so does the text.
Pro Looks smashing
Terminals are often very dull looks wise, not so with terminology.
Pro In-terminal video, picture and thumbnail support
Thumbnails, pictures, and videos can all be rendered in-terminal, based on the directory listing or mouse interactions. For instance, using "ls" on a picture folder will produce a list of thumbnails instead of only the filenames.
Pro Splitable
You can split windows, like in terminator.
Pro Visually customizable
It is very customizable in every aspect of the visual options.

Pro Integrates well with Enlightenment WM
Terminology is part of the Enlightenment WM packages. As such, it integrates really well with Enlightenment and other tools in the package.
Pro Block copy
You can copy text in blocks.
Pro Copyfree licensing
Terminology uses the Simplified BSD License. As it is a copyfree license, it tends to minimize license incompatibilities, legal compliance requirements, and various other complexities that may make it difficult to understand certain licenses.
Cons
Con Uncertain future
The original developer, Tony Houghton, declared the death of Roxterm on 2016-05 at https://sourceforge.net/p/roxterm/discussion/422638/thread/60da6975/?limit=25#3fc9.
In 2018, work began to resume on Github rather than Sourceforge (https://github.com/realh/roxterm/issues/1) but the future maintenance is uncertain.
Con Not for regular users
ROXTerm is made for power users who spend most of their time on the terminal. For a regular user using ROXTerm it would be an overkill.
Con Configuration is sometimes complicated and non-obvious
There's a "Settings" menu for configuration, but more options there would make it easier. Downloading themes and extensions from the official repo would be a big plus.
Con No True-Color support
Not able to display a modern full range of colors, yet.
Con Scrollback is completely nroken
Scrolling back the emulator inserts random lines from other places in the scrollback buffer in between the actuall output lines. Thus it is impossible to see a correct copy of the previous output.
Con No scrollbar
The lack of scrollbar in Terminology makes navigation difficult. But you can use keys for it.
Con Too many bells and whistles
Some people feel that Terminology has too many features that are not suited for a terminal, but for a window manager instead. For instance, viewing thumbnails, watching videos and gifs, and other similarly flashy things just feel like eye candy and should not be part of a terminal emulator.
