Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
