A lot of what the newer hosts provide is making your SPA or other JS framework app 'just work' without extra config. E.g. your build generates /index.html and the host will redirect all other paths to that file.

Also, if it's about cost then whatever cloud bucket plus CDN is going to be typically free and will scale to infinity for very cheap. Everyone dreams of a random blog post being on top of HN after all.

I suppose whether that's simpler depends on if you are familiar with the cloud offerings, but many people are through {dayjob}. For me, I'd rather use similar tooling for work and personal projects, so I don't have to think too much about it.
