DuckDuckGo is awesome, I advocate for DDG as much as I can, and I switched completely a few months ago both on my phone and my PC, but I'm genuinely curious about how you were able to completely switch. Unless you also use the !g command?
I'd love for there to be a "permanent !g" option, because Bing (DDG's default engine) just doesn't cut it. Like, at all. And it's not like I do fancy searches all the time, or ever really. But unless I am searching for a very popular, basic term, most of the time DDG's results either show nothing relevant at all on the first page, or there's one or two results that are relevant, often times the most relevant (like, say, a product page for a product I'm searching for) being shown pretty far down on the page, with third party sites being up top.
In either case, I try !g and immediately find what I'm looking for on the front page. Like it's a whole new world. At this point I am using !g 90% of the time and it gets frustrating; I have half a mind of switching back, but I really don't want to do that, because Google needs to go.
Even when I add "site:xyz.com" or (gag) "site:reddit.com", while DDG's results are better in these cases, just in case I'll try "!g" to see if I missed anything and... bam, even more relevant results I never saw before.
I think Apple needs to enter the search engine business. Bing is just not good enough, and Google is evil. I've moved away from Google Maps, Gmail, Chromecast, and anything else Google I can move away from... but it's the best search engine by far and it's the one instance where it really does make me less productive if I use the alternative.
