Best CS Phone Number for you?

I am new to Sprint. I just got signed up on a Sero plan. Basically I have seen all the listed Sprint phone numbers and am wondering which one works the best for you? Specifically I am thinking about hold time and whether they can resolve your issue or whether they have to transfer you.

I have been calling 877-888-1518 (supposed a WLNP number but they seem to do regular CS) and I usually get no wait time. A person picks up and generally they have been very helpful and seem like they know what is going on.

How about you guys?

P.S. Sorry if there is already a thread like this or if this is the wrong forum.
