Current account choice

Hello everyone, I have a question. I currently have 2 checking accounts - one DKB (because of the credit card) - and one Sparkasse. The savings bank account is currently a thorn in my side - I would like to change the one with the DKB sooner or later, but one thing at a time. I travel a lot for work (including abroad) so I have to be able to rely on my cards. So my question is - to what extent are reviews relevant to choosing a checking account? Background of the question
