• Synonym競うきそうNeutralVerb for pitting skills against each other — technique, price or rank all work, as in 「技を競う」; 競合 stays businesslike and covers overlaps.

• Antonym協調きょうちょうNeutralAntonym: coordination and compromise between opposing sides — the opposite of 競合's mutual vying.
• Antonym協力きょうりょくNeutralAntonym: joining forces for a shared goal, as in 「業務協力」 — the opposite of competing through 競合.

Use 「競合」 for firms or products vying in the same market, or for plans and functions conflicting or overlapping, as in 「競合他社」 and 「予定が競合する」. For competition in general pick 「競争」, and for personal one-upmanship 「張り合う」. The written 「角逐」 suits contests for rank or hegemony, 「挑む」 a challenge you initiate, and 「競り合う」 a dead-even struggle. The antonyms 「協調」 and 「協力」 point to cooperation instead.
