Upgrading from Nikon Z6 (original)

[scarlettanager]

My Z6 is getting a little long in the tooth, especially considering how much better autofocus has gotten in the years since it came out. I'm likely going to stay in the Nikon ecosystem since I have a couple of decades of lenses and familiarity, but can anyone speak to getting a Z6 III vs saving for a bit and getting the Z8? Seems like unless I'm planning to do pro work, the Z8 might be overkill, but is there anything truly useful that I would regret missing if I go for the less expensive solution?
