I think if I was in your shoes I would be thinking is there any way Option 1 is going to work out. That sounds preferable to me. Responsive supervision, and that positive and passionate vibe you describe, is priceless.
BUT - it seems as though Option 2 is in the bag... and you don't want to miss your opportunity because you hung around waiting for Option 1 and it didn't materialise.
What I'd suggest is:
Contact Option 1, explain that you have had an offer from another University, but actually, if they can make you an offer, you would take it and reject the other.
If they can't speed things up, as long as I felt OK about the arrangements (very important), I'd take Option 2. Is there a reason why you would like the second supervisor to be from another department? If you can justify why you'd like it, then why not ask about it? It is your PhD after all - you are entitled to a say about who your supervisors are.
In my personal experience (and everyone's will vary on this forum - so I stress, it is an opinion based on my own experience), it is the ones who are highly responsive and positive, and who have more experience, who make the better supervisors. My very experienced one has been able to see the bigger picture and, informed by their experience, give very smart advice that I generally feel very confident about taking. Also, liking someone (as long as it lasts) can be more important than it sounds. When you like and respect someone, and they are responsive in an appropriate way (i.e., suggesting a mutual regard/respect), it makes it a whole lot easier to work with them/be supervised by them. Just on your brief descriptions, that is why I would feel very inclined to go for Option 1, if at all possible.
Good luck!
