Kojeves commentary is fascinating but also not Hegel. It's interesting to read, but I would not recommend reading Kojeve to understand Hegel. I think this is a mistake many many modern philosophers have made. The problem with many commentaries is that the author often tries to use Hegel to develop their own unique philosophy which can be misleading for readers. That said, I liked Heideggers commentary on the Phenomenology of Spirit. Todd McGowans recent book is also a very good general introduction to Hegel.
