I've used both extensively and what makes me lean towards Vue on new projects is the reactivity system. It seems that with React you always have to wrestle with it to not do too many re-renders, but Vue is more likely to update only the parts of the dom that need updating out of the box.

With composition API and Vue 3 bringing typescript support and hooks to me it's a no brainer to choose Vue.

One other thing is that I've seen people who are normally doing only backend pick up Vue in a day or 2, but React takes longer to grok. You're probably likely to find more people who have already learned React than Vue though, due to its popularity.

React also has a bigger community but I haven't felt that I was lacking when looking for Vue libraries.
