| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. |
