I voted ER, for an obvious reason.
The New Grad Residency program sounds absolutely wonderful.
For tele, 1:4 ratio is OK...1:6-7 could ***really*** stink...plus, why do they have so many bonuses? Usually places that pay so much more are doing so for a reason - they can't get anyone else to work there, so they pay the big bucks.
I do agree that it is valuable to have other experience besides ER...either as a student or a nurse. You'll have a broader perspective on what happens after pts get out of the ER, which means you can take better care of your pts while they're still there.
But, if ER is really what you want, go for it. Especially with what sounds like such a great opportunity.
