The Philippines have been in a continuous state of low to high level insurgency since the Spanish first landed. No victories there.

Government suppression of those segments of the populace who dare to stand up for themselves are Pyhrric victories at best.

As to Malaya? The Brits finally conceded that they had no legitimacy or right to govern Malaya and finally removed the office of the high commissioner and also ensured that the ethnic Chinese populace had their civil rights issues addressed to the degree that they no longer supported the insurgents. They removed the thorn of external colonial intervention from the paw of the oppressed and aggrieved segment of the populace that the insurgency arose from.

There are always many motivations for why one joins an insurgency, but causation? That almost invariably derives primarily from how government governs and how some or various distinct and significant segments of the populace feel about the same.

True victories are where government evolves to address their shortcomings. So yes, of all your examples, Malaya is the best of good COIN; but not for the reasons found in military accounts of that insurgency.
