I’m not an accountant, but I think the distinction is that the MoR will handle both the collection and remittance of tax for you, including filing any necessary paperwork. You get money deposited in your bank account, and you deliver product to customers, but you’re not worried about remitting taxes.

If Stripe collects the tax and sets it aside, that’s helpful, but it still means you have to figure out which jurisdictions you owe tax to, and figure out how to get the taxes delivered and reported to those jurisdictions (“remitted”), which can be a headache, to say the least.
