The thing I noticed most is that in Denmark, Danish sites follow both the letter and thespirit of GDPR. I was looking at trying to pay my electricity bill the other night and got told that because my version of FF sent the Do Not Track header, they'd automatically "objected" to all cookies and branding beyond necessary ones and I didn't need to do anything else. Those big banners have a simple "yes to only necessary" or "yes to all" button at the bottom.
American sites on the other hand tell me either "tough, take our spyware if you want to see this site, or to to a restricted list of five pages" (which I'm pretty sure isn't legal under GDPR); throw up the gauntlet of 1000 tick-boxes, infinitely nested, or say "you're from the EU and we can't serve you page".
The problem is cultural. I've de-googled myself as much as possible, but I don't like the fact that all of my real mobile device choices are written in California and made in china.
