I've been seeing a lot of OpenCode fuzz on HN lately, because of Anthropic disabling their access to the private subscription endpoints, and I confess it made me feel like I could be missing out on something though I can't tell for sure.
There's also Amp Code who seems to be picking up traction, and, although more on the IDE side, I have tried Kiro through AWS Credits and it surprisingly outperforms Claude Code for me in some cases but didn't fully bait me into the switch.
Codex works as good as Claude Code for me but I like Claude's UX and Opus 4.5 better.
Are there any reliable Coding Agents benchmark out there? What is your take?
