Which is better IKEv2 or IPSec?

IPSec is considered secure and reliable, while IKEv2 is extremely fast and stable – IKEV2 offers quick re-connections when switching networks or during sudden drops. Thus, a combination of IKEv2/IPsec forms one of the best VPN protocols that exhibits the advantages of the two.
