Sorry, but number of commits don't say anything about the quality and direction of a project.

React has been around for much longer than Solid, and also much much more popular, with many more contributors. It's also the pioneer of virtual DOM reactivity, when you're a pioneer there bound to be some trial and error.

It can also be argued that SolidJS has a higher bus factor, as it's still very dependant on the creator (Ryan Carniato).

Sharing my experience... A while ago, I wanted to build an app using SolidJS 1.4 but got stuck because of a list mapping bug, ie. child list not updating IIRC. I reached out to Ryan, he said that he knew about the bug and had a fix coming in the next release. I couldn't wait, so I had to port what I had to React and call it a day.
