If you forward to Gmail then you can still receive mails to the other service should Google disable your account, if you do it the other way you're screwed.

I see.. I was thinking along the lines of migrating away from google and having the forwarding in place for contacts that didn't update your address yet. Or that couple of services you use but forget about. So you can slowly move everything to the new address over time.

And particularly, you can still access things like password reset on other accounts tied to that email.
