The verdict
If you run a Dutch company and have no proper business account yet, pick Rabobank first. Your accountant and the tax authority both recognise it, and every invoice needs somewhere to land. If the account already exists and the bookkeeping is the mess, pick Twinfield, especially when your accountant already works in it. In that case the accountant is a stronger reason than any feature list.
Do not treat it as either or. Before you switch banks, check that the Rabobank connection you need is supported by your bookkeeping package. Before you commit to Twinfield, ask for current plans, because you will not find a simple public price list. I would choose the order rather than the winner: bank first for a new company, ledger first for an established one.
