I have the special DVD set of Blade Runner, and I think I have watched every version, that is Original US and International, Director Cut and the Final Cut released in 2007
I was watching the Theatrical International version, and I think at the end it's the best version. The other two are a bit "cold", without personality, too aesthetic, almost Kubrik like. The voice over is actually sparse and not that present, even though originally I thought it was, and it actually brings a focus that is not there in the other 2 versions.
The ending is actually quite appropriate. In the other versions, that is Director Cut and Final Cut, the ending was actually lame, giving no direction or a clean end, almost feel like they didn't know what to do, so they let it there unfinished, almost amateur like.
Soundtrack didn't age a bit, quite amazing.
