Hi @Traveller1, great to have you here!
Some people have moved from Evernote to Obsidian and have had great experiences. I personally love Obsidian, but I worry that its main features might not be the best fit for you. It isn’t intended to be used mainly for document storage, but note creation and linking ideas together. If you just want to store documents and webpages, DEVONthink might be better for you since Obsidian is meant to be interacted with instead of being a file storage.
On the other hand, if you would like to try to do more creating instead of collecting, Obsidian would be great to give a try. It’s helped a lot of people transition from being collectors to creators. Ultimately, just choose the tool that better suits your needs.
Let me know if you have any questions! I’d be happy to help
