Among the most noticeable differences between the AT&T and Intel assemblers for the Intel CPUs is the way they refer to source and destination operands within an instruction. Under the Intel format an instruction's source and destination operands appear on the right and left of the comma which separates them, respectively. Under the AT&T format, these roles are reversed: source operands appear on the left and destination operands appear on the right. Was one of these better than the other? Why or why not?
