Lambros Petrou, Software Engineer at Facebook and ex-AWS, has a good post comparing Netlify, Vercel and AWS as jamstack platforms:
If you focus only on Jamstack applications, my recommendation would be to go with Vercel. It has amazing performance, and the zero-config approach really does wonders for the majority of the popular frameworks. Recommending Next.js for one more time 😃If you are going to find uses for Netlify’s add-ons, then it’s a great choice as well! Really, Netlify and Vercel are very similar and you cannot go wrong with either.
