Are those alternatives free or self-hosted?
Anecdotally I have heard that many clients prefer Statamic's and CraftCMS' editing experience over WP.
They also get free suppport. You don't get that with WordPress.
From what I've seen, almost all hosting providers now offer one-click installs for WordPress.
Aside from that, what's the UX like for a client spinning up a new WP site on GoDaddy or Bluehost vs. a new Wix, Weebly or Squarespace site?
In the end most of this is pretty subjective. If you like WordPress keep using it and recommending it. I used to love it and don't anymore. I think my clients get a better value using Statamic or one of the other options I've pointed to.
