The best one is the one that works best for you. HTML editors vary widely in terms of features, methodology, and target audience. There is no way to recommend a single best tool for everyone. If the program gets the results you want and you understand how to use it, then it is right for you.
Some factors to consider in choosing a program are:
- Does it provide the ability to easily preview your site? (Don't take this for granted; some tools make this surprisingly difficult.)
- Does it offer the option to publish your pages for you via SFTP or rsync, or will you need an external program for that?
- If you want to use PHP or other dynamic content on your site, will the program make that easier or harder?
- Do you like and understand how the program works?
While we still use vim every day, as of 2024, our own websites are largely maintained using the JetBrains IDEs. We can enthusiastically recommend them for complex dynamic sites, and they also provide some support for editing HTML, but they have drawbacks. They aren't for site design or layout, they carry a substantial learning curve, and they're not exactly cheap. So they aren't the best choice for every situation. Visual Studio Code is free, high quality, and seems to be very popular, but also emphasizes programming over page design.
