Impact is another good choice. It's bold and stands out, making it suitable for titles and headings in comics. Arial Rounded MT Bold can also work well as it has a friendly and approachable look.
I think Helvetica Neue is nice for comics. It's clean and versatile. Another option could be Century Gothic, which has a modern and stylish appearance that can add a contemporary touch to your comic.
Comic Sans is a popular one. It's easy to read and gives a fun, lighthearted feel.
