Can only say after trying them both that CBQ is much better then Doha bank. Easier procedure for the money withdrawals in the branch, excellent internet banking with international transfers (Doha bank still doing it old fashion way with a hand writing form that takes ages to fill), international ATM withdrawal in EU (Doha bank has a blacklisted countries policy that nobody really knows why is some country actually blacklisted....). These are just the ones i can quickly think of
