My use case: for 100$/year, I can provide my family and my parents plenty of reliable cloud storage for their documents and pictures. With office suite thrown in as added bonus. I know of no other alternative that would provide equivalent of 6x1TB for such a low price.
I was also of that opinion for a while, but took the decision to move all things to a dedicated backup service instead. The lock-in with onedrive is palpable. So I swallowed the pill, downloaded all our files (very slowly...) and backed them up properly instead, with a service that will send me a hard drive with my files upon request.
I'm curious, what did you select, and how is the UX? With OneDrive, it looks like any other folder in your windows/mac computer, and the built in gallery of the Samsung phones my family uses will transparently sync to OneDrive. Other apps on Android can also "directly" access OneDrive files, but that sadly needs support from the app. And it all is available for access online via browser.
My main goal is to prevent data loss if a device is ever stolen / fails beyond repair. And being able to tell your non-technical family members to "put important documents within this folder" / "log in here if you need access outside your normal devices" is low enough of a barrier so that they actually do it.
