Kai's verdictA-tier for designer-led sites. S-tier if animations matter.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.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
