Given that the D15 is an option, it's going to be more about the looks than performance vrs an aio or other large twin tower. The D15 is the highest rated aircooler there is, but understand even it is going to be pushed if you decide to push that cpu, a 5GHz OC is not uncommon for that cpu, and it'll pull 200w when pushed to the limits.
The D15 is a 250w cooler, so it's plenty able, but there's not much headroom. A 280mm aio is @ 350w and and a 360mm is closer to 400w. That'll have enough headroom that the fans won't need to be closing on max speeds, and still maintain decent temps.
And that's the trade off. The D15 will get slightly better temps across a wider range of loads, but can't compete with the top end ability of the big aios.
So each will have its advantages and each has its disadvantages, neither design having a clear, overall win, just specific wins and losses. Which generally ends up in a contest of looks and aesthetics.
