I would describe it as the simplest fastest least buggy terminal available that supports tabs and unicode. So I have tabs for each machine and tmux sessions on each of those machines, kind of 2-dimensional. As you'd guess for something with a full name of "unicode-rxvt" the unicode support is bulletproof, perhaps the best out there of all possible terminals although it varies over time.
As simple as possible, and no simpler.
It does nothing that impresses other terminal authors. Other terminal authors seem to prioritize user experience beneath keeping up with the achievements of other terminal authors. So it is completely incapable of 3-d widget animations, or transparent viewing of 3-d accelerated VDPAU movie rendering via transparency, or any number of things that are extremely technically challenging and "desktoppy" and very impressive to other terminal authors but users primarily see as something that makes it slow and crash alot and complicated and distracting.
