ANP or GNP?

I am looking into getting into a Masters program as soon as I graduate in December and I'm not sure what path to take. I know that no one can decide that for me just want some input on the difference between an Adult NP and a Geriatric NP. I understand the obvious difference but my question is would it be better to get the ANP so that I have more options available to me as far as employment or go the GNP route because I know I want to work with Geriatrics? I have heard that I can work with geriatrics with the ANP as well, so would it be better to go that route since I would have more jobs available to me upon graduation. Just looking for opinions so that I can see it from someone elses point of view. Thank you.
I think there are programs that combine Adult and Geriatric NP together. Something to check out?
