That's the conclusion I came to as well. I use Dropbox but I found the notice about increasing restrictions a couple months ago, and looked at iCloud and OneDrive.
Other than what you mentioned, OneDrive always offering Office Online and the apps with a lot of shared storage for other users. And iCloud gives you that device backup for multiple people, another thing it grants you is the ability to use iCloud email. The web interface is the cleanest and most dignified looking of all major vendors. The snag with iCloud email is their calendar isn't the best, you can't have it email you reminders for appointments as you can with Outlook.com and Gmail. iOS notifications only, which is a very annoying restriction. I like to be notified, but also have an email sitting in my inbox on more detailed instructions on what may need to be done.
Starting from scratch today with the goal being zero-cost, I'd pick Outlook.com and OneDrive. If I'm willing to perpetually pay, iCloud.
May have to get on that and at least get over to Outlook/OneDrive, but tough to leave Gmail when everything is all setup as you like it. Dropbox is easier to leave, they're pushing it by decreasing value rather than improving it.
