Until recently they seemed to be deprioritizing features I cared about in favor of e.g. Paper, which seems designed for some other type of user. So, when my company was choosing a provider I didn't really have any compelling arguments I could make in favor of Dropbox. Maybe this signals that the tide has turned again.
Exactly, I've always preferred Dropbox because unlike Google Drive, Box, etc they handled files and handled them well. The aesthetics were clean and simple (the new site looks like someone killed an eggplant and based a website on it).
But I've always wondered why they don't expand more on their storage basis for new features? Say email storage and backup (with say an optional web client interface) that supported regular email clients like Thunderbird/Outlook (ok, handwavy magic outlook support). Or a password service that sync'ed via Dropbox (1Passwd was great for a long time this way until I moved to a Linux desktop from a macbook). Their MS Office integrations are actually pretty great. Paper was cute at first, but doesn't build on their storage-first basis by storing say regular markdown files somewhere.
I still think the killer feature that will actually stratify these perfectly similar services will be seamless entire device sync. I have my files clumsily positioned behind my onedrive folder and use shortcuts, but macos insists on the default folder locations for some things.
As clumsy as it is, its still great to be able to grab any devce in the world with an internet connection and access all my files in a few mins. Refining that would change the game for this type of service.
Just in case you've not thought or knew about it, have you tried using folder symlinks on macOS? Might be an answer to those situations where you have to have files in a special folder or its subfolder, but unfortunately will require setup on each device. On Windows there are different folder symlink types available as well (an `mklink` command line program makes them), plus the common things like documents and pictures are actually "collections" where you can add several folders for the Explorer to combine when viewing these collections
