Most likely: those who swear by it have brain damage by x86-ism.

 It's the oververbose, bas-ackwards intel syntax that one does swear at.
 The AT&T syntax that BGB noted above is far superior.
 YMMVO.

x86 asm, as used in MASM and DEBUG, was the first assembler language O used, I found it very familiar that
   mov ax,bx
or
   mov ax,[bx]
or
   mov ax,[bx+1234]
all correspond nicely to
  a = b
  a = *b
  a = b[1234]
I.e having the target on the left is the only one that makes sense to me. I can read the wrong one of course, but I have internally translate everything before I can grok it.
