We'll have to agree to disagree. It's not glamorous or super fun to develop on, but is in very battle-tested. WordPress runs 40-something percent of all sites, and WooCommerce is the most popular eCommerce system in the world. I host hundreds of enterprise clients on WordPress.

"Battle-tested" wouldn't be the word I'd use to describe WordPress. It's easy to make a website with it, hence the 40-something percen of all sites, but it's just a huge pile of bad patterns mixed together and nothing more.
