How to read this table
Two rows decide most of it. Where your data lives determines what happens to a decade of records if the app is discontinued or the company is acquired. Export formats determines whether you can act on that. Everything else is preference.
If you are weighing this up more generally, the six checks before trusting an app with your history covers the questions that apply to any app in this category, not just these two.
