Why are saying that Firefox or even Chrome reskin can't compete with Chrome? I haven't been using Chrome for maybe 10 years or more, so I'm genuinely interested. Even if you hate Firefox, something like Brave is felt the same way but without google's garbage. I heard there are new guys in town like Helium and other Chromium based browser which choose to remove telemetry, support manifest v2, adblocks and so on.
The browsing experience without constant upselling some trash and proper adblockers are magnitudes better.
The most compelling argument I've heard is around security, while Firefox does sandboxing, it is not as comprehensive as what went into Chrome.
I'd still choose Firefox over it for the reasons you've mentioned.
