aterm
aterm is a highly configurable and lightweight terminal emulator. Some features include pseudo transparency with tinting, a configurable scrollbar, and fully customizable fonts. Generally speaking, aterm has more cool non-essential features while xterm has more practical features. In particular, xterm doesn't have transparency. At the same time, aterm's lack of practical features contributes to a smaller memory footprint than xterm has.
Not all window managers honor a graphical program's request to be borderless. While KDE goes as far as allowing the user to toggle a checkbox to remove a window's border, the Unix Window Manager doesn't even honor a programs request to be borderless. This makes it hard to make a terminal emulator look as if it's part of the desktop background. Although I didn't have any success with it, a patch has been circulating the Internet that allows for aterm to be borderless even while being run in a window manager that doesn't support this request.
aterm's default look is a little drab. I recommend launching it using the following options:
aterm -tr -sh 20 +sb -fn courier
In plain English, this launches aterm using transparency with 20% of the root window's graphic, no scrollbar because Shift + PgUp/Dn work too, and the courier font because the default is ugly. Use xfontsel if you want to see what other fonts are also available on your particular system.
