to centrally keep track what articles I'd reviewed - because without it I might forgotten what I'd reviewed after a while.
to check whether those articles that I'd reviewed have been published - if they have been published & I can gain access to a copy, I would like to read the final outcome of the published article.
to learn how my recommendations have impacted the quality of the published article, what are the recommendations that I'd missed but other reviewers be able to catch etc - all these can help me to improve my review skills.

Yes, it is useful. As an early career researcher, I find it useful to keep track of the articles I have reviewed. It is easy to retrieve the record when I am required to submit it to funding organisations and other assessors.
They sent me one article. The article was having many basic mistakes. I send the details of such mistakes. The corrected article was resubmitted. Afterwards it was accepted. They send me one certificate for this.
I find it useful as a reviewer to keep track of review records. Also, as an author, it helps to look up potential reviewers in a field when it is a requirement for the journal to which you wish to submit your paper.
I have recently joined Publons and I find it very useful in designing a uniform systematic way to conduct a review. The fact that you receive some recognition for the work you do is a plus.
