#4 Counterpoint: The upper card is already crowded
While Finn Balor could probably have less of a glass ceiling on SmackDown, where he wouldn’t automatically be cast behind Braun Strowman, Brock Lesnar, and the Shield alumni, it’s still not entirely clear if he would, or even should get to shine on top of SmackDown. On the face side of things, one could reasonably argue that AJ Styles and Daniel Bryan are at least as worthy of being on top. On the heel side of things, Samoa Joe is probably winding up his time in the main event, but there are still figures like Randy Orton, The Miz, and Shinsuke Nakamura it’s not totally clear Balor should be booked ahead of. That’s not to mention guys like Andrade Almas on the rise, and perennial main event threats like The Big Show waiting to be deployed on top again.
It's a credit to SmackDown that the brand is so stacked with talents who could reasonably be slotted as the WWE Champion. It also, however, makes it more difficult to factor in adding a guy like Finn Balor to the mix, and especially shooting him straight to the top of the brand.
