I write PHP for a living and I only write headless apps with Symfony and Laravel. Blade is an awful template engine with a primitive parser. Twig is tolerable, but for me nothing beats the DX of Inertia with Vue.
It also has various magic for router links that do partial refreshes and working with classic (non-json) forms and whatnot. I use none of those, I'm all about json and useFetch() instead, and Inertia's pretty good about getting out of your way when you don't need it. It lets you write as much or as little in SPA style as you want, it's more or less your favorite JS framework as a view layer directly without having to interpose another view as a middleman (the middleman is there, but it's all implicit: you add the @inertia directive inside your <div id="app">, and that's it)
