The primary reason I’m looking for an alternative to WordPress is its reliance on PHP. A language so awful I wouldn’t let it anywhere near my computer if I didn’t rely on WordPress for my blogging. Using PHP as the substrate for your CMS/blogging platform guarantees you’ll have day one security problems. Just look at all of the WordPress plugins and themes that have horrible security flaws (e.g., revslider).
Amongst most of the website builders, another name that comes to mind is Squarespace. The versatile builder for blogs, portfolio sites as well as online stores, has managed to rise in its popularity in the recent years. Despite the huge difference, this being a closed source software while WordPress is an open source; it certainly is a great alternative to WordPress Page builder. That’s right, for the casual users the overall functionality and the flexibility is the main aspect.
