What banks that you prefer?

Does it ever come to your mind that actually do we really need a number of banks instead of one? I mean well for me, we should as to cater for different of needs i.e, savings, operational and stuff. Nonetheless, I used to have 5 banks in my custodian and nowadays it has been reduced to 3 banks and I might be adding another one later. These are the 3 banks that I used nowadays:-

Maybank - I used this bank since my final year time (late 2007) when I was in UiTM where the transition from Bank Islam to Maybank. I just into it their ever-popular and ultra efficient online banking portal which is the maybank2u.com. My first credit card also from this bank and I just love it ever since, the short falls of it as i found at the rates and the charges are quite high and some times you didn't notice the hidden charges, maybe because of their good service. Nonetheless, I will continue to use their service.

Bank Islam - This is the bank that I used since I started my UiTM days (mid-2005) as this is their official bank after they change from Affin, and yes, I like their Islamic banking features and used it as my no-touching-saving-account. Since, I have a problem with their online banking features, I just can't comment much on it, but I bet it have improve much since.

Bank Simpanan Nasional - My first formal saving account is from this bank which I opt it when I was in foundation level (mid-2004) and I still used them for my travel savings and sometimes most of my friend will make fun of me as my `student' bank is still active, well it show that I'm a loyal customer.

I have plan to opt for one more bank next year and still in the midst of research and comparison stages as nowadays there are a lot of shariah-based banks in the market and their offer are also quite lucrative.

So what banks that you prefer? and why is that?
