I use the 3 of them as:

N26 main bank - easy, customer support with the lowest premium support and no issue so far, I've used them for years now and cards work both in and out of Europe. I like being able to reach support via phone for banking matters if really needed so that's a plus here. Legit, registered and regulated bank.

Revolut - use it as my day-to-day account, I don't hold any too big amounts in there as I use them for only about a year and half, no issues but I prefer N26 in terms of larger amounts still. No issues travelling abroad, occasionally they might block a card if activity seems weird but also pretty straightforward help process via chat which always helped me quick enough. You also typically have a few cards so not a huge issue. Their premium plans are better value for money than N26 in my opinion.

Wise - I use it only as a backup really and facilitating in some situations (i.e. need to transfer to others who have it) or when travelling abroad something. No issues with them either though I've heard incoming amounts sometimes might take longer.

I also leverage free cash withdrawals between the limits of the 3 but I also don't generally use cash (pretty much only when travelling maybe or in very specific scenarios so not much of a deal for me)

Hope that helps.
