Depends what you want. They're different cars. I like the growl of the V8, the B&W stereo, the relatively quiet cabin on the highway or around town when I want it, plus the comfier seats (imho). For $118, I'm not sure the F90 has the options I'd personally want that make it that much better, but it's still arguably the best all around car BMW makes right now. $112k is silly money for even a 50 Jahre car, plus I'm not on board with the design language or the interior UI.
I'd still go F90 here.
