There is no right or wrong answer when it comes to choosing the best site to start a blog, as the decision largely depends on your individual needs and preferences. However, if you are looking for an easy-to-use platform with a wide range of features, WordPress would be a good option. Additionally, its popularity means that there are plenty of fellow bloggers out there who can help you get started and provide support. If you are more comfortable working with custom code or developing your own websites, then Tumblr might be a better choice.
It is user-friendly and has a large community of bloggers who can offer support and advice. Ultimately, the best site to start a blog depends on your personal preferences and needs.
