Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for model-shopping. I use this for every prototype before committing.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
