GrokBot is S tier because it's just more reliable than the other agents when it comes to doing repeatable routines. OpenClaw is C tier because it's just not that reliable anymore. It used to be really good. I was a big fan of it, but the next tool has actually surpassed it. And that next tool is Hermes. So Hermes, I would say, is A tier. And the reason it's A tier is because it has the most context. It's open source. You can connect to whatever you want. You can use whatever model you want. And so it's the most flexible, but it still comes with its own problems. Codex is S tier. And the reason for that is because it has the most powerful models from OpenAI, and it's the best harness out there for getting things done. Claude is A tier. Sure, it has Claude Code, it has some of the best models out there, and the reason I like Claude is because it's still the best when it comes to design, and it does— it's also very token inefficient as well. So that's why I put Claude as A tier. Whisper Flow is B tier. I mean, I use it every day. I use it to just basically dictate, but it's not like it's anything that is from a product standpoint way better than other products. Granola is B tier. I mean, it does a good job with taking notes, but other than that, I don't really use it for much else. And I still do use it every day though. Instinct agent is A tier. It is a newer agent that can handle more complex tasks. For very complex tasks, it's easy to set up and it's easy to use. I think Instinct is A tier. Perplexity is D tier. I mean, frankly, I don't really use it anymore. I get plenty from Claude. I get Plenty from OpenAI, and I don't really. I used to use it as a search engine, but frankly, I get what I need from Google because Google is getting better every single day with its AI mode. So I don't really use it that much. Gemini is C tier because it does a good job with watching videos. It does a good job with design and images, and it's good. It's catching back up slowly again, but they did kind of fall behind for a little bit. So that's why I think they are they're a C tier right now.
