Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
