Note you can access startpage results from DDG with the "!s" bang.
I rarely use region specific DDG, but when I do, I find it ok. With DDG I can manually enable/disable and switch the region, while Google guesses based on my IP - very annoying, given that I frequently use VPNs. (Of course, if you're logged in to Google, you can specify region/language/etc., but if you don't want to be tracked and delete their cookies or use the browser in private/porn/incognito mode, then it'll just assume that you are looking for Dutch things in the Netherlands, because that's where the VPN exit is...)
