So far I've used Next.JS to build out what I had already done using Nuxt. Everything I've done so far has backed up what I thought I knew about React—it's broadly similar to Vue, but more technical and less structured. I still prefer Vue but it's early. I haven't gotten into CSS yet where I expect there to be more differences.
I do like how Next.JS just works out of the box—I had to do a lot less setup of my dev tools than I'm used to. Next.JS also has some nice advantages over Nuxt. The hybrid export is really nice.
I'm also deploying this to both Heroku (in hybrid mode) and Netlify (in static mode). I really intend to use Netlify but I need to at least be basically familiar with Heroku for a work project.
