It really depends on your needs. Are there many alternatives more flexible than WP? No. But that is begging the question. The vast majority of people don't need the kitchen sink that is WP, and would be better served by utilizing one of the many products and platforms that have cropped up to fill more specific niches since the inception of WP.
Just need a blog? Maybe want it to be a newsletter? Ghost, Medium, Substack, etc
Want an online store? Shopify, Checkout Page, etc
Need a sexy website that doesn't take coding? Squarespace, Framer, etc
You get the idea.
