My feel is that svelte 5 is simpler and less cumbersome than 4.

It's (another) move in one right direction.

When i had some confusion migrating was that the previous way was done poorly (by me) and svelte5 made that work perfectly, basically with no code.

My whole app is using very little svelte code "over the hood". It just magically work. No server side rendering. Static adapter. Way to go.

Also their discord server is very helpful and organised.
