Great question. The funny thing is, 6 years ago, if you'd ask the same question (and I'm guess that's what you're coming from) the go-to answer on HN would've been Rails / Django something. Where both will allow you to build a basic crud app in 20 minutes.

Since then, everybody has gone heavily into various javascript stacks, and the norm has become to deal with 20 different packages to build (somewhat) the same thing. And the first hour will easily be spent researching different dependencies, trying to get them all to work how you'd want etc.

It's easy to see this as a horrible backwards progression, but the reality might be a bit nuanced.

The easiest way to get a basic crud app up and running these days is probably still some sort of rails/django stack. But today's requirements in terms of UX / dynamism (is that a word?) require you to end up building things differently, so even if you get up and running fast with a rails app, you'd end up having to build up a pretty hefty JS stack in the end, so you'd basically be delaying the inevitable.

So the answer really depends on what level of "good enough" you're going for.
