If you're familiar with the SKEWB,
I would like to know whether it's harder or easier than the classic 3x3x3
Rubik's Cube (I suspect it's simpler, but it has fewer symmetries).

It took me a while to give out a working algorithm from it. Surprizingly
my moves have very little use on Rubik's, and if the SKEWB wasn't as
simple as it was it would be really tough to work out. Fortunately,
due to its simplicity I need to remember only one code sequence.
