Hi @Steven61 and welcome to SF
If you are French resident, you must ensure that your Wise account is notified as a foreign bank account to the Fisc when you complete your tax return here (on form cerfa 3916) but I’m sure you already know that 
The clear advantage with Revolut over Wise is that Revolut for French residents now has a French IBAN and as such opens quite a few more doors for you.
Some on SF have reported that they have experienced delays with Wise. Perhaps you’d like to read through this topic to read more on this.
