I'm completely unqualified to offer anything. The last time I tried React was four years ago, I've never used Svelte, and I'm currently using Vue 2. Vue 3 supposedly fixed a lot of the most surprising/annoying things about Vue 2.

But I'll say this. Thank goodness I don't consider myself a frontend dev.

The selling point of Vue was that it's supposed to be less of a learning curve compared to React. It's "closer" to regular HTML and JS. Except it's not really. You still should not mutate component "properties". If you ask anyone any question about anything, the answer is "use Vuex"- even if it has nothing to do with what you're trying to accomplish. There is definitely a learning curve around its reactivity model (this has supposedly improved with version 3). And I found some stuff just awkward, e.g., Vue components have lifecycle hooks that "support" async/Promises, but the lifecycle doesn't await the Promises, so I had some initialization that had race conditions and I didn't realize why/how.

I don't know if that's good or not, honestly. I just know that Vue2 has certainly not made me enjoy frontend work any more than I did before (which wasn't much).

The big gotcha for Vue2 was the performance when you wanted to display a list of like 10,000 things. I like to tinker with data and a lot of my day is spent on an sql prompt inside of emacs watching results sets of 1,000 rows or 50 columns just fly by so I can search them visually. Having to remember to "freeze" things for performance or create simpler "views" of the model I'm playing with is sometimes jarring.

This tripped me up recently too. Somehow I'd got it in my head that Vue (2) would selectively re-render sub-trees within a given component if no dependencies within the tree had changed. I had a table functioning as a datasheet (not even that big—about 20 columns by 100 rows) that was absolutely chugging and I couldn't work out why, because nothing within the table was changing very often. Extracted it to its own component and all the performance issues went away.
