DDG mostly. I'm not unhappy with Kagi on any particular technical aspect, but I'm not happy about the fact that I learned that it was operating out of Serbia (it was often listed as being based in the San Francisco Bay Area; this appears to actually be a residence of the founder, not where the employees and offices are). I'd be much more comfortable about them getting in practical legal trouble if they wound up retaining data after saying that they don't if they were operating in a US or EU or something legal jurisdiction. I posted about it to !kagi@programming.dev a while back.

If they moved operations to the US or somewhere like that, I'd have no problem using them.
