Question Ranking
Pros
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 Drag and drop
ROXTerm supports dragging and dropping items into the Terminal window.
Pro Lightweight
LXTerm is the official terminal for the LXDE desktop environment, which is a very light DE in itself. So LXTerminal is a very good choice for lower-end systems.
Pro Multiple tabs support
LXTerminal supports working with multiple tabs and tab-based navigation.
Pro Built-in transparency
Pro Customize-able background/foreground colors
Pro Customizable keyboard shortcuts
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 Not very customizable
LXTerminal, like XTerminal and UXTerminal, is not very customizable and extendable (at least not as much as other terminal emulators).
