A router uses it's processor to encrypt/decrypt packets which could be detrimental. You can purchase an AIM card which offloads that into hardware. The ASA already has that. Either will work just fine. I usually decide but what else the device will have to do (ie mcast, advanced routing, netflow).
Hope that helps.

if you need advanced routing or QoS go with a router, otherwise, i prefer the ASA because it's already a hardened device.
also, since you weren't specific, other reasons one might choose a router is that it can do GRE and DMVPN.
