Likewise, I'd pay that as well (I'd like no ads as well, but tracking is the main issue for me).
Similarly, I do have DDG as my main search on all machines and devices just out of principle, but its region-aware searching (I'm in NZ, and often only want NZ results) are very close to useless in my experience (with NZ as the region ticked, it will still return results from .ca and .co.uk domains, which I would have hoped would be almost trivial to remove), and Google seems much better in this area (but not perfect).
Similarly, there's often technical/programming things I'll search for that DDG doesn't have indexed at all, and Google does.
Google also seems a lot better at ignoring spelling differences (color/colour, favorite/favourite) than DDG, which is often (but not always!) useful.
