It sounds like, all things being equal, you should probably go to Kentucky. Place matters a lot, especially during a PhD. You're continuing to grow during this time, and you need to make sure you're in a supportive environment to do that, and that looks different for everyone. Just because you go to a "lower rank" program doesn't mean you won't end up with a good job. A lot of it has to do with what you do while you're there (like getting teaching experience, publishing, conferences, etc.). BUT the most important thing is finishing. There's a reason why 50% of grad students don't finish PhDs--it's because it's really tough. So, do your future self a favor and go where your heart tells you and where you will be able to live your best life. And, to me, that sounds like Kentucky. Just make the decision--and soon--so that whoever is on the waiting list below you gets a chance to consider the program you decline. Not as many people are lucky enough to be able to choose between two great programs, and by making your decision, you'll be able to give someone else a long-hoped-for admission.
