20 minutes vs an afternoon is probably not a great gauge for making technology choices.
I highly recommend watching Rich Hickey's "Simple Made Easy" [1] talk which covers how the right ("simple") choice may not be the "easiest" (convenient, most familiar) one.
I don't mean to be an arse, but if you agree with my point, then maybe you can see why I disagree that your "that and" is a valid strike against React/in favour of Vue.
Simplicity makes picking up the unfamiliar easier. You can't accurately deduce from time alone that the time to pick up Vue was based on familiarity with similar libraries.
