If you are comparing apples-to-apples (e.g. setting up pre-installed Linux verses pre-installed Windows, or installing Linux to installing Windows), I would argue that Linux has been in the lead for many years. Setting up a reasonable desktop distribution (Fedora, Ubuntu, etc.) is no more and no less technical. Linux distributions won't encourage you to create online accounts, try to upsell you online services, or bombard you with questions about privacy settings.
From my last experience with macOS: on a technical front, macOS is simpler to reinstall. The online account setup and upselling is far less intrusive (perhaps to the point where you can legitimately consider it as a beneficial setup step for the end user). Perhaps macOS has the lead, but it is a marginal one.
