How to tell them apart
あげく（に） emphasizes a long, often troubled process leading to a decision or outcome, typically with verbs of deliberation like 考えたあげく or 迷ったあげく. 末（に） stresses sustained effort or struggle over time before a result, fitting nouns of extended hardship as in 交渉の末 or 熱戦の末. Swapping them can feel off because あげく leans toward personal wavering, while 末（に） suits a drawn-out battle or negotiation.
- あげく（に） Use あげく（に） when someone wavers or deliberates for a long time before finally deciding.
- 末（に） Use 末（に） when a long, hard effort or struggle finally produces a result.

あげく（に） ageku ni
Ultimately, after everything is said and done
あげくに expresses that after a long period of struggling, hesitating, or repeating an action, a disappointing or unfortunate result finally occurs. It emphasizes wasted effort or an unexpected bad ending. It follows the past tense form of a verb, as in 迷ったあげくに or 悩んだあげくに, with に being optional. It is not used for neutral sequences or positive planned outcomes.
-
さんざん迷ったあげくに、結局何も買わずに帰った。
After agonizing over it forever, I ended up going home without buying anything.
-
彼は何時間も悩んだあげくに、会社を辞めることにした。
After hours of struggling with the decision, he decided to quit the company.
末（に） ni
Following a lengthy process or considerable effort
末に expresses that after a long period of thinking, discussion, effort, or trouble, a final result or decision is reached. It follows the past tense form of a verb, as in 考えた末に, or a noun with の, as in 議論の末に, and に is often optional with little change in meaning. It is common in formal writing and speech, and implies difficulty before the conclusion, so it does not fit routine sequences.
-
私たちはよく考えた末彼の申し出を受け入れた。
After much consideration, we accepted his offer.
-
長い議論の末ようやく彼らは結論に達した。
Only after a long dispute did they come to a conclusion.
