Yandex for every day things that I know will be able to be found easily. Also, their image search is awesome, I didn't know the name of a part, so I took a picture of it, dragged it to the image search, and it easily found similar images which allowed me to get the part name. If I have something fairly technical, or I need to get specific information and be shown the web page where it specifically says something (think specific laws etc), I'll ask Microsoft Copilot a question along with "and provide the specific web pages where this is confirmed".
