I think there are probably still more Angular devs, but I'll be interested to see how it evolves in the next few years.
And I'm sure you did fine work, but small business print shops are not exactly industry trend setters. What difference would it make in the bigger picture if you had chosen Handlebar for that project?
Sometimes you have questions on StackOverflow that compare eg Angular with React, and they usually raise a lot of good points, but they are missing several dimensions:
* the products evolve, but the SO answers often don't
* the trends change as well, so what was seen as best practice 1yr ago may not be well regarded now
* you do not have an objective representation of how many people are actually supporting each technology
I think there's definitely something to be done in that space.
