I switched from DuckDuckGo to Qwant a week ago and so far I'm happy with it. I'm in the US and it does a great job returning search results that are relevant to me here, even though it's intended for people in Europe.
I also switched from Gmail to Posteo, ChatGPT to Le Chat and Firefox to Waterfox.
I plan to replace Google Drive with Nextcloud, sometime in the next few months when I have the time to set it up.
Google Maps will be the hardest to replace. I've tried 8 or so competitors and they all pale in comparison.
