I took a trip with a friend, and tried to convince her to upgrade, and she wouldn't budge, and we stayed at Pop. For her, it made sense, for me it didn't.
I use the pools, and LOVE hot tubs (especially after all the walking in disney), she didn't visit the pools at any time.
I used the food courts for coffee, and prefer to have a TS location at the resort for a place to eat for an evening. She never stepped foot in the food court that I took a 15 minute walk to and from every morning.
I personally, having experience at BC, wouldn't base my hotel choice on just buses. That's one aspect of the trip. Your rooms and beds will be larger, you have a better and more fun pool (plus hot tub), more dining options, and a hotel that is much easier on the eyes. (I, personally, was not a fan of the over-large icon statues everywhere. much prefer the landscaping and beauty for my resort choice) I think that for just $200, it's not even a question, definitely upgrade.
