Alternative course at King's or the course I applied for at Leeds?

I recently got an update from KCL saying that I hadn't made it onto their PPE course (which is what I applied for), but that I was being considered instead for religion, politics and society. They then gave me an AAB offer to do this. I also have an AAA offer for PPE at Leeds and an ABB offer for PPE at royal holloway.

I'm trying to plan for the possibility that I won't get anymore offers, and Royal Holloway is going to be my insurance no matter what because the grades are safe. However, I can't decide whether to firm Leeds, which I don't like as much as KCL, or KCL, where the course isn't what I applied for. I don't dislike the religion politics and society, but I much prefer the option to focus on politics in a PPE course. If I don't receive offers from my other choices (manchester and warwick) which should I firm out of KCL and Leeds?
