Spoken like someone who has not read the others :P.
I'm not going to lie, I read almost exclusively modern philosophy, I haven't read nearly any ancient greek philosophy, but I am a huge fan of the Socratic Method and there is some timeless wisdom in the knowledge that "the only thing I know is that I know nothing" that I think transcends all other possible philosophies. I do not think, nor have I found, anything wiser that can be said.
