Well, sendgrid-nodejs is a more popular repository.
However, Nodemailer is the most popular module for sending email using NodeJS. I have been using it for several months and I am very satisfied.
If you are worried about the future of your application, you should think that Nodemailer is used not only with Sendgrid, but also with many other competitors. Therefore, if you have a problem with Sendgrid, you can easily switch to another email delivery service without having to learn another API.
Therefore, I suggest you use nodemailer-sendgrid-transport, and if you find errors, correct them with PR: P
