Having worked on the Drive team, I can assure you Google Apps (which includes GMail, the Docs editors, and Drive) has much more than 50 million. A quick search on public figures for these services will give better numbers. Edit: Those are Apps for Work numbers, excluding consumers - obviously you can't compare just a subset with a total.

Why does Drive lack where Dropbox has succeeded (efficient, reliable syncing)? (Honest question, since you mentioned you're on the Drive team)

In my opinion:

User Interface. Dropbox presented a beautifully clean metaphor for how your files get synced. It doesn't matter if you understand what "the cloud" is. My grandmother understands: "put things in folder, folder available elsewhere".

On the other hand we've got Google Drive. Is GMail using Google drive? Is Google Photos using Google Drive? Why don't folders other people have shared to me not appear in my folder? Why isn't 'Shared with Me' the same as "Mine". Is Google Drive the same thing as Google Docs?

Not to mention - Dropbox really pushed the "Desktop App", while Google Drive pushed the "Web First" approach. Add on referral bonuses, Dropbox had some good solid adoption - well, at least among free users.

I use both extensively - Dropbox Pro for everything personal, and Google Drive for everything at work, and I still get confused about the where I saved/shared files to in Google Drive.

I used to have a ton of issues with reliable syncing but I haven't had any issues with it in the past year or so.

What do you mean?

Drive sync works fine like Dropbox, at least on Windows and Mac.
