It works to prevent internet access from that ip. However I can still ping 8.8.8.8

In a very general sense, DROP may be preferred to REJECT when you are dealing with protocols other than TCP or UDP.

For TCP, a firewall can reject a packet by sending a TCP RST in reply. However, for all other traffic, an ICMP message has to be returned for a rejection. One effect of that is that you may be replying to ICMP echo requests with an ICMP message from your firewall. It could be that what you're seeing isn't a reply from 8.8.8.8 at all, but a reply from the firewall.

Try dropping the traffic instead, and see if that effectively blocks outbound traffic.
