I've been using start page for the past few years as a default, but find myself typing in google.com->tab to search a lot of my day. The difference between pasting in a random golang compiler error into startpage vs google trained me to google all of my software issues. The biggest non-technical hurdle at this point is google maps. The ability to type in an address and get a map with directions and nearby businesses has been pounded into my brain and when I use DDG or startpage with an address I generally end up sighing and pasting it into google.
