Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
