It is worth being fair about Blocksy, because it earned its reputation. It is fast and light, it is Gutenberg-native so it works with the block editor instead of fighting it, and its customizer is deep, with real control over headers, footers, typography and spacing. Its WooCommerce styling is strong, the free version is generous, and Pro is reasonably priced. For a developer or a designer who likes working close to WordPress, it is a joy.
