Choosing a laptop for work and there to find freelance job sites is key. My advice to you is to look for a powerful processor, 16GB of RAM for smooth operation and SSD storage for fast booting. Weight and size matter if you're mobile. Macbooks are popular but expensive, consider a Windows or Chromebook as well!
My personal Top:
Apple Macbook Pro (Classic choice for web dev, but on the pricier side)
Dell XPS 13 (Powerful and portable Windows option)
Google Pixelbook Go (Great budget-friendly Chromebook)
