The world's best intelligence agencies: MSS
It is headquartered near the Ministry of Public Security of the People's Republic of China in Beijing. The mission of the MSS is to ensure "the security of the state through effective measures against enemy agents, spies and counter-revolutionary activities designed to sabotage or overthrow China's socialist system."
One of the primary missions of the MSS is undoubtedly to gather foreign intelligence from targets in various countries overseas. Many MSS agents are said to have operated in Hong Kong, Macau, and Taiwan and to have integrated themselves into the world's numerous overseas Chinese communities.
At one point, nearly 120 agents who had been operating under non-official cover in the US, Canada, Western and Northern Europe, and Japan as businessmen, bankers, scholars, and journalists were recalled to China, a fact that demonstrates the broad geographical scope of China's network.

The world's best intelligence agencies: Mossad
It initially began by tracking down Nazi war criminals and exfiltrating them to Israel for trial. Mossad is most famous for having taken out a number of PLO operatives in retaliation for the attack that killed eleven Israeli athletes at the 1972 Olympic games in Munich. However, this agency has other success to its name, including the acquisition of a MiG-21 prior to the Six-Day war of 1967 and the theft of the plans for the Mirage 5 after the deal with France went sour.
The Mossad is regarded as one the most successful and effective spy agencies in the world. Recently, Mossad courted controversy when 26 alleged agents were captured on the closed circuit television of a Dubai hotel where senior Hamas leader Mahmoud Al Mabhouh was found murdered. The UAE police showed paspports from 6 different countries who protested the matter.

The world's best intelligence agency: ISI
Its success in preventing a full scale invasion of Pakistan by the Soviets is a feat unmatched by any other agency throughout the intelligence world. Even the mighty KGB, the best of its time, failed to counter the ISI and protect Soviet interests in Central Asia.
The ISI has had no double agents or defectors through out its history, considering that the whole war campaign it carried out was funded by money earned by selling drugs bought from the very people it was bleeding, the Soviets.
The ISI has protected Pakistan's nuclear weapons since formed and it has foiled Indian attempts to progress through internal destabilization. It is above all laws in Pakistan.
Its personnel have never been caught on camera. Its is believed to have the highest number of agents worldwide, close to 10,000. Among all the agencies mentioned on this list, the ISI is believed to be the least well funded.
