Localamos: If you want a less crowded banking hall, then try FCMB.
.
If you want a bank with Good branch network, then you might go to first bank.
.
If your choice is customer service, you can go to fidelity.

My experience with Unity bank is that they don't have a great ambiance, But their service delivery is pretty Good.
.
Access bank and UBA have the highest number of ATMs. You could choose either of them if you are particular about reliability of ATM services.

I disagree with you on this. From my experience with first bank in kaduna, zaria and abuja, i can confidently say they are so poor in branch network. All their branches in zaria and kaduna usually have network ish. There is no one time i have entered any first bank branch in these three states i have mentioned, that i come out satisfied with their services. and speaking of queues, they have the worst ever. Especially in their Coomassie branch here in abuja. GTB to me is very okay in all standards, yes they have queues sometimes, but i have never spent more than 10 minutes on it, unlike spending an hour on queues in first bank. Gtb is customer and time friendly.

this is so nice

This shouldn't be taken lightly by our government. how long are we going to keep losing innocent souls untimely in this country? and have those in power fold their arms and mope.. smh
