Good to knowI get what you mean, but it's exactly the same. You can completely build an image with everything you want on it, air gapped even, with trusted installers and drivers, then sysprep away to remove the user scope. You then have a complete white glove (industry term) build, with all the apps and drivers on, untouched by the internet, untouched by users, image.
Never having used sysprep
I can't say which way would be easier
Or have advantages over the other
I was just pleased my way works
And seems to do everything I need it to
