I'm not on the fence about buying them at all.
I'm on the fence about whether to buy the 9-movie Best Buy set - with 1 redundant movie, since I already have the "Rise of Skywalker" 4K disc - or if I should get the 8 individual titles.
That's it. Unclear if there's some compelling reason to get the 9-movie set - like it has a book or something not in the individual sets...
Buy the box and sell your redundant copy of RoS.
