There are pros and cons to starting a blog versus a YouTube channel. Starting a blog is less expensive to maintain, as you only need to purchase an domain name and hosting, whereas starting a YouTube channel requires purchasing an account, creating a YouTube account, and filming and editing your videos. However, starting a blog can be more difficult to get noticed by search engines, as they typically favor YouTube channels over blogs. Additionally, starting a blog takes more time to develop content than starting a YouTube channel does.
However, once you have created some content and established yourself as an authority on your topic, starting a YouTube channel can be easier to grow because you can monetize it with ads. Overall, it depends on the topic and type of video you plan to create which one is better for you.
