But, my long term view is that Svelte (or Svelte like) library will win out in the long term. Getting code back to basics is a great theme/trend. It's what made me like Vue to start with.
Cost to start. The first time I tried Vue (after trying a bunch of other libraries) I had something working in minutes. React required I learn many other things before even getting a "hello world" to function. Straight html/js connection. JSX is a nightmare.
Integration with existing systems. I work with hundreds of thousands of lines of code in a very messy old system. I was able to gut pieces of jQuery and nearly drop in replace with Vue.
Template focused development. I don't care how super duper awesome the "render" function is. I don't care how fast or performant. I am need to build a tool that I use for a couple of years and then throw away. (long story short, having a build pipeline is a detriment in many apps that I work on because their lifespan is so short)
I may be an amateur, but that is where Vue is genius. I don't have time to learn 20 new entire systems, 10 new build platforms, Node.js (and all that entails) just to get a reactive app to replace some super old jQuery junk.
I am now more capable than before, but after managing so much code for so many years, I want things _less_ complicated, not more. Nearly 100% of the code I wrote 20 years ago is gone now, replaced, rebuilt and redesigned. All the Vue I will build today will be gone in a few years, that is almost a certainty. So I have no budget for messing around.
The list can go on, but I am sure I will get harrassed with this about how React can run live and doesn't need compilation, ha. I tried it, what a mess it was. Learning the quirks of JS is bad enough, learning the quirks of doing 'JS exactly like React/Vue' wants you to? Ugh, that just sucks so bad I want to pull my hair out. The less a library I have to deal with the better. The more pure and simple code is the better. /rant.
All of them are approaching the same problem from different directions and paths. If each discovers something new and useful, the others can decide if it would be a good fit for them.
It's all wins all around, so I don't understand the disparagement.
