the book I read before it that had strong oppinions was talking mainly about Dennis Washburn and Aurthur Waley I think?
what I'm looking up says that the Royall Tyler one might be your best bet
it's a complete translation, it's the newest one, and it seems like the whole goal of it was to do a better job of getting the text closer to what the origional book was than the two main full english translations before it
and supposedly, at least according to what I am reading, it also has extensive notes about the history in it too?
so maybe that one is your best bet
in fact I am almost certain that isn't the one I have read and I think I want to give it a shot myself XD
in fact it was available on my Kindle so I picked it up XD
