One reason, heartbeat is standard in many distributions (ie: RHEL, Centos) and vrrp and keepalived are not. It might be overkill for just IP addresses, but being supported in the base OS is a plus that shouldn't be discounted. If you have to support heartbeat on other servers, using heartbeat for places you have to share resources is easier than using vrrp for some and heartbeat on others.
