Quick question. Most of us know the pattern of keys to press to force a restart on an unresponsive computer. However, I've seen two different orders recommended and I'm curious if there is any difference between the two orders from the computer's standpoint, and if so, which is better.

I learned the "Raising Skinny Elephants Is Utterly Boring" method. Namely, hold down Alt and SysRq and then press the following patter of letters, leaving a second or two in between: RSEIUB

The pattern I often see on these forums is REISUB.

Which is the best? Does it matter?
