How good are Credit Union Banks

[John Paul]

Hi,

We have been with Citibank for past 15 years. The kind of interest what they pay for savingplus account is 0.10%

Wondering if we can move to another bank where they pay better interest rate on the savings account.

I read about these Credit Union banks and people say you might get better interest rates.

1) Are the credit Union Banks good compared to regular bank w.r.t. savings accounts interest rates ?

2)  Which are the popular Credit Union Banks in USA ?  Or anything in Chicago area ?

3)  Based on some articles I read they say Credit Union Banks might not have ATMs like regular banks. But if they are paying

    more interest rates compared to regular banks.  We can leave large cash savings in Credit Union Bank and still leave some

   cash in regular Banks(in case we need to use for ATMs or any other services).   Unless Credit Union Banks now a days does

  provide same facilities like regular banks.   Correct me if I'm wrong.

4)  If you are currently using any Credit Union Bank, which one is it and do you like it ?

Thanks in advance.  Any other suggestions are welcome.
