If you already own a Zen 3 capable motherboard and aren't interested in PCIe 5.0 and have no need of additional 4.0 lanes for storage, then the case for doing anything more than buying a Zen 3 for an upgrade isn't very good.
However for anyone on older hardware where they will need a new motherboard + CPU, I think it would be dumb to not do an Alder Lake upgrade given these results and current pricing. This would pretty much apply to anyone on Intel who is planning to upgrade, anyone on Zen 1 or 1.5, and many on Zen 2 if their motherboard does not support Zen 3.
That is a pretty narrow set who might upgrade to Zen 3 based on empirical results and not just feelings. It really just leaves people who have Zen 2 and compatible motherboards and don't intend to do more than a CPU upgrade, maybe those who have a 5600X and want to go to a 5900 or 5950X, where Zen 3 makes sense.
