It depends on what you like...
I've never finished it myself, though I've actually just started reading it again.
Do you already have a copy? You might want to browse through different editions to see which is most reader-friendly to you.
For example, I have a verse translation, which is very pretty, but it can be challenging in parts.
It's definitely a classic, and referenced all over the place, so, really I'd be amiss not to recommend it.
But... it might be slow-going.
So, really....
It depends on what you like.
