I’ve had the exact same experience! I’m getting to use some new JS SSR frameworks at work (Remix) but I keep using rails for my own things. Gets out of my way.
Remix is pretty nice too, and I appreciate it for bringing Rails-style SSR to style in the React world before RSC, but the power of Rails is from having a complete platform to build your apps on. I don't need to string together five different libraries to implement authentication and e-mails, that comes more or less built into Rails.
