I'm actively using computers with high-end Intel and Apple silicon. The benchmark data doesn't capture real-world use. Apple does have its drawbacks but has a history of protecting and advocating for user privacy. The M1 laptop I'm using SMOKES an older generation i9 in performance, even while running the same software through a VM. The i9 chews through batteries like crazy and gets wildly hot in the lap in use. The M1 machine gets warm and a charge goes much further. Hardly "little to no" efficiency gains. They're significant in my use case. Can't argue with criticisms of price, upgradeability, and repairability with Apple, though. There are still some good laptop manufacturers making laptops with upgradeable RAM. I hope that Intel or AMD will keep innovating and try some radically new architectures that bring their chips closer to the efficiency of the ARM stuff. I hope Apple will make their stuff more repairable, and at least make the desktops upgradeable. If price is a major factor in your purchase, then Intel is a no-brainer. If not, you should give the Apple silicon a try. You may be surprised. I was.

No comparison. The apple CPU's come with so many strings attached for little to no performance or efficiency gains. They do look pretty but the flexibility of PCs is unbeatable. The added privacy issues of American corporations make it less of an option to consider the glass prison that is Apple.
