It depends if your use case is more to sync with yourself or if sharing with other people is important to you. I feel like Dropbox that does way better, the UX of iCloud Drive is still horrible (Seeing the progress of sync, sharing with people UI,...). I use iCloud sync for things I want to eventually access on my phone, but I see it as "eventually consistent" as sometimes things just don't show up for a while. I can highly recommend Syncthing if you don't need to access on mobile but only between computers.
