Never liked Real since before the first Galacticos, generally can't stand cunts who buy their way to success and Real have been the original plastic club in that sense. Being Franco's favourite club and a Neonazi horde as their Ultras doesn't make them sympathetic either.
Bayern are scum, the ultimate evil in this world. To properly despise them I guess you'd have to live in Germany and be surrounded by their filth 24/7 though. If a team consisting of Hitler, Stalin, Mao Zedong, Pol Pot and the likes played in the Allianz Arena I'd still be waving giant flags and burning Bengal fireworks in the away section.
