Why does it have to be one or the other?
I use both. EagleFiler is a much better Finder than the Finder is with EagleFiler’s three pane interface; wonderful for storing emails (I think that was its original function) and things I need but don’t need now. I’ve spent a long time curating what I have in EagleFiler, and I’m not going to leave.
Evernote is much better for display and use on the phone and iPad and I can capture things when I’m on the road, like receipts and client information. I use Evernote for access to a subset of information I need when I’m on the road. I’ve got EagleFiler’s Files folder saved on OneDrive and aliased back to the Library folder (works like a treat!), but it’s harder to access information on the phone from there.
When I get information on a client for a period of time in Evernote, I save it to a folder in EagleFiler.
Hot (Evernote) and Cold (EagleFiler) storage. Can’t live without either.
