Ultimately, the beauty of a search engine is in the eye of the beholder. If @russell1066 is happy with DDG results, it really doesn’t matter what Leo or any other pundit says. My personal opinion of DDG shot way up after they adopted the “site” keyword a while back.
One difference is that “Apple silicon” is not solely a CPU to plug into a motherboard. Leo and Rene are discussing this in MacBreak Weekly #733 (9/29/2020) around 52:00. The Apple [silicon] H1 chip in Apple’s newer Airpods and Beats headphones is tiny and has tiny power demands. Nevertheless, this 10-core (!!!) chip does a lot: ANC, “hey Siri”, automatic switching between devices, audio sharing, spatial audio, and a Motion API to send the wearer’s head orientation/acceleration to an iPhone or other devices. This is Apple silicon; it’s a sand castle that can be molded into all sorts of functionality distinct from a monolithic CPU. Rene has some great comments in that MBW segment about the useful kinds of edge computing that Apple silicon can provide.
Another difference is that Apple silicon Macs will have the entire iOS and iPadOS arsenal of apps available immediately when those new Macs are released. We were discussing that here. This will have strategic value for iPhone/iPad users to also choose an Apple silicon Mac. This synergy is something that the fastest Zen 2 chip cannot compete with. The app-compatibility is also a great feature for individuals who may never bother with any mobile device. Odds are low that your local bank will ever make a Mac-specific app, but every bank already has an iOS app. 
With Catalyst and SwiftUI, Apple’s case for running the same app everywhere will only get stronger.
