We have inherited thousands of WordPress sites, which teaches you quickly which themes age well and which turn into maintenance debt. This list weights speed, block editor support, and long-term maintainability alongside the design flexibility that usually drives the first choice.
How we chose
- Performance: default page weight and Core Web Vitals without extra tuning.
- Block editor support: how well the theme works with core blocks and full site editing.
- Customization: header and footer builders, layout controls, and starter templates.
- Maintainability: update cadence, code quality, and how painful it is to change later.
- Ecosystem: companion plugins, documentation, and community size.
Verdict
For most new sites, Astra, GeneratePress, Kadence, or Blocksy will serve you well, and the choice comes down to taste: GeneratePress for the leanest build, Kadence or Blocksy for the richest block-based design controls, Astra for the widest template library. Choose Twenty Twenty-Five if you want to commit fully to the Site Editor, and Divi or Avada only when the visual builder is the point and you accept the lock-in that comes with it. If you would rather not choose at all, Seahawk’s WP Services team builds on these themes every day.
