DDG is definitely behind Google still, although it's come really far in a few years. I agree with most of what you're writing, but personally I'm okay with it not replacing 100% of my searches yet, got to start somewhere and I feel this is an acceptable point to switch at.
I started feeling like I had all my eggs in the same basket. Google has my email, it knows where I want to go and when (Google Maps), it translates stuff for me, and it knows what I search for. While it doesn't really affect me that Google has all this information, I've become more and more uncomfortable with the fact that they do.
So I figured if I had a choice of two search engines, where I get satisfying results in both of them, and one of them doesn't track me, why go for the one that tracks me?
I'd gladly do the same switch when it comes to Gmail, but I really really like Gmail's web interface, haven't gotten over that hurdle yet.
EDIT: I also switched from Google Chrome for pretty much the same reasons.
Recently switched over to DuckDuckGo on all my devices. Tried to do the same thing several years ago and found it didn't really work out, but this time around it is so much better, both when it comes to speed and results.
If anyone has doubts because they tried it years ago, I'd say go for it again.
To be fair, at least in iOS, the edge swipe wasn't implemented until iOS 7. Imgur has the same problem, annoying as hell, but that might be a reason to why they haven't fixed it. (Even though iOS 7 is soon a year old)
There's a similar thing in Sweden, called Swish (https://www.getswish.se/). But it's a cooperation between banks, and you link it with your phone number, the transfer is instant, you have to identify using something called Bank ID.
Square Cash seems nice, but I prefer the approach of Swish.
