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）means that after a long process of doing something, often worrying or hesitating, a final result follows, sometimes an unexpected or negative one. It attaches to the past (ta-form) of a verb, and に is optional. The examples often pair it with さんざん or 迷った, showing lengthy deliberation before the outcome.
-

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）indicates that something happens after a period of time or effort has passed, as in 週末に. It follows a noun, and the に can be dropped in some uses. The examples show it attached to time nouns like 週末.
-
彼女は学年末試験に落ちたのではないかと心配している。

-
私たちは毎週末になるとよくスケートに行っていました。
