Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for speed. When latency is the product, start here.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
