The interest rate various at each bank, some offer a better introductory rate for the first month, the rate also depends on the amount you have in the account. If you email the Banker (Alper he will tell you Fortis rate)
I have monitored rates over the last 2 years and have always got a better or equal rate at Fortis than the other banks I used.
I am biased though because Alper started as my account manager and is now a good friend.
