Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for solo + free. The best free option, hands down.
