What is the most successful ant?

Could you elaborate on the intriguing question, 'What is the most successful ant?'? I'm fascinated by the intersection of biology and success metrics, particularly when applied to the world of insects. In the vast ecosystem where ants occupy a significant niche, which species stands out as the most accomplished? Is it their ability to cooperate and build complex societies that defines their success? Or perhaps it's their adaptability to various environments, their resilience, or their remarkable ability to farm and cultivate resources? I'm eager to hear your thoughts on what criteria you consider in determining the 'most successful' ant and which species you believe fulfills those criteria.
