I, personally, really like Jack. With John, I felt that I had to play through the game with high honour, because that seemed like the kind of person John was. With Jack, I definitely felt that I had more freedom to do what I want.

That said, I think the primary reason that Jack receives so much hate is that he wasn't involved in the story enough. With John, we got an interesting backstory, then we played through the game as him and I imagine most people got the feeling that he was badass (therefore, we felt badass). After John's unfortunate, but necessary, demise, we're thrown onto Jack and we don't have much to do. In all likelihood, the player has probably completed most, if not all, of the Stranger side-missions, so, as Jack, all we have to do is bounty hunting and mini-games.

I think if the story had continued somewhat after we take control of Jack, he would have been a much more likable character.
