Definitely a review article, since it involves a "review" systematic of the information published about it. An original article, involves the presentation of new data and analysis thereof.
Dear @Najmul, let me bring here some new types of articles that were proposed by Elsevier, such as data articles, software articles, material and method articles...
How new article types help make science more reproducible?
"Unfortunately, traditional journals don’t give you enough space to thoroughly describe your datasets or the methods or software used to generate them. As a result, research data is rarely provided in a reusable format and often lacks descriptive information. Furthermore, many types of data, such as replication data, negative datasets or data from “intermediate experiments,” often doesn’t get published because it has no place in a traditional journal...
To address this concern, Elsevier has launched a series of peer reviewed journals under the Research Elements Program that makes it possible to publish data, software, materials and methods and other elements of the research cycle in a brief article format...
Our new article types give your previously hidden content a home, but there are lots more benefits. Firstly, it’s simple to submit, because you can pull together and use the notes you keep as you collect and analyze data, write software code or adjust research methods and protocols during experiments. To make it even easier, all the Research Elements journals have an article template, which can be found on the relevant journal homepage."
Obviously review articles are more informative than original research papers. The former deal with current status of researches carried out in a specific topic in a broad way without going into minute details. At the same time each original research article also includes a brief review of research specific to the subject of research. I think both format are important. The review articles cover several original research papers published in the past.
I agree that a review article is more informative. A well written review articoe provide a critical analysis the literature in a specific field through summary,,classification analysis and comparison of many articles.
6 Article types that journals publish: A guide for early career researchers!
"In the competitive world of academia, you are expected to start publishing early in your career. Although original research sometimes takes years to complete, it does not mean you cannot have any publications to your credit till the time you complete your research. There are different types of scholarly literature, some of which require original research (categorized as primary literature) and some that are based on other published work (secondary literature). It is important to have a clear idea about the different types of articles that you can publish in journals. This will help you understand the ways in which you can disseminate your work and identify what kind of article would be suitable for your study.
The types of publications are different in different fields. For instance, a clinical trial is possible only in the field of medicine, while an empirical study is more common in the field of social sciences. It is important to remember that not all journals publish every kind of article. Specifications about the types of articles published can be found under the guidelines to authors section on a journal’s website. If you have a target journal in mind, you should check whether it publishes the kind of manuscript you are planning to write..."
I agree with the views of Manmohan; certainly both are important. But, the question is which format is more informative. It is always review article which are more informative as compared with the original research paper.
