The advantage of using the templates of these websites is that HR can screen resumes more quickly. All models are roughly the same, and the screening speed is faster. In addition, using the template generated by the website to send your resume HR can see the form of text, and your word file must be an attachment, which is actually very important.

The disadvantage is that if there are no special highlights or skills on the resume, it is likely to be directly screened out.

In addition, as you said, the typesetting effect of these websites may not be as good as your own design. In addition, I think the worst thing about using website templates is that many required column settings don't need to be filled in. This kind of filling is not only cumbersome, but also may adversely affect your job search.

To sum up, our opinion is to submit your resume in your own typesetting way. (provided that HR can open your attachment or typeset it in the form of text)
