I'd avoid Oasis AND f***ing heavy metal. Tbe Beatles are better for beginners and you can actually enjoy the learning process.
Not sure I'd put The Beatles that far above Oasis for practicing your strumming as a beginner. Beatles might be the next step for an Oasis fan after learning their favourite Oasis songs.
I agree that Heavy Metal technique is pretty much only useful for Heavy Metal guitarists though. Well, them and possibly flamenco and jazz manouche guitarists (see Rodrigo e Gabriela - began playing in metal bands before making their careers in flamenco iirc? and also see Les Doigts de l'Homme for a French gypsy jazz band with metal links).
