Virat Kohli and his equation with 'strike-rate'

Virat Kohli scored a 67-ball hundred against the Rajasthan Royals, the joint-slowest hundred in the IPL hundred. His strike rate in that innings was 156.94. However, Rajasthan Royals easily chased the target with Jos Buttler scoring 100* at a strike rate of 172.41. What does that say about their innings? Should strike rate be the only yardstick to judge a batter's performance?
