I’m a former DDG user (maybe for 2 years?) who switched to Kagi in December (and have paid for my first month already). I preferred DDG over Google (for most searches, Google was better at rare searches; in addition, DDG got worse over time), but prefer Kagi over both. I almost always get what I need, and the personalization features (specifically ranking sites higher/lower linked to your account) are great. Really need to find the time to play around with lenses, but I have heard good things ;)
