DESK NOTE

The pairs are interchangeable. The wrappers are not.

Within each row, you are buying the same investment exposure. The choice of wrapper affects how you transact, what minimums apply, and how taxes flow through. Pick once based on your brokerage and account type, then stop looking at the comparison and start contributing.
