When I first switched from Google to DDG I found myself using g! all the time as I wasnt happy with the results, especially local such as finding a specific shop in my area etc. I dont recall using g! with Kagi, and when I was bored and compared the Kagi search result with Google to see if I was missing out, it turned to be the other way - I realised I was actually getting a much wider spectrum of results. I discovered many cool websites and blogs I never knew excited thanks to it or rather thanks to the fact that they show you what’s relevant to your search unlike Google that shows what they think is.
