Should I upgrade to Aura?

[steiner03]

I have a MyZone card and i got an offer to upgrade it to Aura card. I don't really find the benefits of this card useful.I am open to upgrade to better or higher or even a different card which has some useful benefits.
So, do i have to upgrade to Aura to get further upgrade offers or will i get other upgrade options if i wait?
I think it's been a month or 2 since I got this offer.
