Honestly, SolidJS is one of the most exciting options on the horizon. The creator wrote the vanillajs implementation for the frontend framework benchmarks so he really knows a lot about the performance implications of implementation details. The great thing about Solid is that it's a lot closer to react with hooks and jsx (I feel like Svelte is learning too much non-js stuff). The problem is that it also has its gotchas. It's much "smarter" than react about re-rendering, which means that it memoizes nodes all over the place and doesn't rerender the entire tree and diff all the time. Instead, it's only rerendering the node that changed (and not even the children of that node unless you set up the children correctly—gotcha). But look at the benchmarks... it's solid!

Ryan Carniato (author of Solid) makes some comparisons to Svelte here: https://dev.to/ryansolid/5-ways-solidjs-differs-from-other-j... and also here: https://github.com/solidjs/solid/blob/809fd5b8683e6f8c338961...
