As a cheap user that only uses the 20$ month subscriptions I started with Claude Code as main & Codex as backup when the 5 hour quota was exhausted.
Then I saw that Codex worked better for me and cancelled my Claude Code subscription. And now for my moderate use (4-5 hours a day with no parallel agents) I have enough with Codex $20 and AMP free if I want to save some weekly quota.
But honestly I usually have enough usage to last the full week without using AMP.
