This is the way I have long seen it. Existential phenomenology argues that existence, that is, presence-to-perception, is phenomenologically prior to interpretation, while hermeneutic phenomenology contends that interpretation is prior to existence; I have long personally resolved the disgreement by considering existence and interpretation to be phenomenologically co-primordial.
