Svelte is better than Vue and React, IMHO, especially for typical startups building typical websites. Svelte is faster to learn, makes smarter decisions, and has compile-time checking.
I teach all 3 to teams, and the top advantages of each as I see them: React for job opportunities and pre-built sophisticated code (e.g. Telerik Kendo), Vue for easy on ramp for JS/CSS/HTML developers who want to phase in dynamics (e.g. sprinkle ins akin to Alpline JS), and Svelte + Sapper for the best developer experience and fastest sites.
