I don't think one is better than the other, but it comes down to average user's expectations from cloud software and from desktop software. My last company was very paranoid about security. Things like never leaving your desktop unattended, changing password every 4 weeks, encrypted disks, encrypted emails, forbidding most of cloud services... All the while happily using Windows and Outlook. Also, although Google knows everything about me, they have so far managed to prevent security incidents, leaks and embarrassing deals (apart being forced to provide backdoor to NSA). They seem to know what they are doing security-wise.
