Godard of course. Truffaut style is somewhat more mature,influenced heavily by literature. Godard is much more carefree, funky, cheeky...he films what he sees around him,he writes whatever inside his heart,his earlier films were inspired by jazz and american pop culture. His dialogues are sharp,witty,observant,poetic,funny,dark. he inspired guys like tarantino,araki,wong kar wai,hartley. where truffaut characters are tiresome,and eventually irritating after awhile Godard's characters are compelling to watch even when they are 'angsty'. 'breathless' is to this day, one of the best film around...rich dialouge,funky soundtrack, hand held, natural lighting. he made everything looked easy and seamless. so Godard is my man.
