I always preferred EOR. Maybe the cute factor, or maybe because I first played with assembly language on an Acorn Electron (and later a full BBC Master Series)

I always preferred EOR. Maybe the cute factor, or maybe because I first played with assembly language on an Acorn Electron (and later a full BBC Master Series) where I think the nomenclature comes from (the 6502 assembler built into BBC BASIC called the instruction EOR). ARM was originally Acorn Risk Machines, and the original designs evolved from the CPUs designed for the Acorn Archimedes range of computers.
