Recommending the greeks and Frege in one breath immediately outs you, and shows your philosophy knowledge for what it is, dog shit. You shouldn't be recommending anything about philosophy to anybody. There is absolutely zero reason to study ancient philosophy unless you're interested in HISTORY of philosophy specifically. What Frege, Wittgenstein, Heidegger and other modernists did to 'philosophy' was short of completely reinventing the field from scratch. The connection to antique philosophy is non-existent because there are no tools in Greek discourses relevant to philosophical investigation. It didn't stop even the most stringent analytics to manufacture said connection out of 'romantic' notions, but really there's no geneology to speak of. Plato is closer to Archilochus than Frege, so much so he's almost verging on a joke (philosophically speaking.) It's doubly funny you throwing shade on Nietzsche, who himself was 'romantically' obsessed with the Greeks for no good reason.
You're right that Nietzsche is ultimately, of devil's party, a poet, but that has very little bearing vis-a-vis academic philosophy.
