N26 vs Wise

Hello, I'm going to germany soon and I have a blocked bank account (Sperrkonto) with Fintiba. On Fintiba's site both N26 and Wise are suggested banks for opening a current account to activate your blocked account. From what I found, I think that both of them don't require "Anmeldung" to activate the account which is very important for me (So that I can access the money as soon as possible after arriving).

Does anyone have any good or bad experience with these banks that could help me choose?

Could Wise being Belgian and providing a Belgian IBAN cause me any problems in germany?

Thanks for your help
