Finanztip.de should be your go-to resource in Germany for questions like that. It's a non-profit, funded by a Fintech guy who decided to start it after his large exit. All articles are written by journalists. It's a real gem.
There are, of course, also disadvantages, like the fact that the new online banking apps are utter shit and offer maybe half of the functionality the old apps offered, but still they sunsetted them.
Advantages are that the have a really good exchange rate when paying with the card in foreign currency. Like really good and they don't charge the 2% tax per transaction that other banks charge.
Same in India. I tried using a neobank but quickly closed the account. They don't have the services traditional banks do and everything was slower than it is in my current bank. My current bank will pick up any paper and signature they need from home or deliver any documents to home the same day.
I get better Forex rate than wise or any startup. The target audience for these neobank are college students or new working people.
For reference, I use ICICI which is the third largest bank in India.
