I switched from Keep to Obsidian as well. It depends on your goals. For me, I was saving things in Keep that I wanted to have forever and I don't trust Google to operate the service forever. The exported data is also not super portable. And there are things I want to save that I don't want on a cloud service. So I switched to Obsidian which gives me a simple and portable file format, privacy, and I trust myself to keep those files safe more than I trust Google.
