Which site is best for option trading?

Can you provide some insights on which site is considered the best for option trading? I'm new to this and want to ensure I'm choosing a reliable and secure platform that offers a wide range of options, competitive pricing, and a user-friendly interface. Are there any specific features or services that I should be looking for when evaluating different options trading sites? Also, how important is it to consider factors like regulation, reputation, and customer support when making my decision?
