💡 Detailed Explanation
"拮抗" (kikkō) refers to a state where two powers are competing against each other with no clear superior. It is the most suitable word for a situation where two teams are of equal ability and the outcome is unpredictable. "対峙" (taiji) means to confront or face off against each other. "肉薄" (nikuhaku) means to close in on or press someone hard. "均衡" (kinkō) means balance or equilibrium, but "拮抗" includes a more dynamic nuance of an active struggle or rivalry between two evenly matched sides.
