Personally I'd like to see both Raylan and Boyd make it out alive. Yeah Raylan hates Boyd, but you can tell there is a mutual respect there. They grew up together, and they have always played a little cat and mouse game. I don't really believe Raylan wants Boyd dead or locked up for life. Everyone thinks this show is going to end with a dual between them both. It could possibly end in a totally different direction. Maybe they do end up with a common enemy, and they help each other resolve it. Once that happens, Raylan gets rid of any incriminating evidence he has on Boyd, and they both ride off in the sunset, in separate directions obviously.
I just think they both will die by killing each other on the last episode, or they both leave Harlan alive.
