The majority of researchers in my country publish their works on journals. In my opinion the publications of research results at high-level conferences are more credible!! Can I have your suggestions??
If the conference has adequate peer-reviewed conference,and the researches published in a high impact factor journal issue, I agree with you that the publication of the results in the conference more important than just published in a magazine.
The multiplication of conferences today is a fact, as is the elevation of costs for participating in them. Assessing the quality of a conference is a much harder task than it is find the quality of a journal. We always must exercise care in choosing either conferences or journals. For journals you can consult https://beallslist.weebly.com/ or https://predatoryjournals.com/journals/. If a journal is listed on these sites, you had better not to submit a paper to them. Open-access is a very common way to get money from authors for publishing papers, but beware of the risks, several open-access journals are predatory (exceptions exist, of course). I have always published papers in conferences and journals. The turnaround for a journal is always much longer, but the resulting paper is always better. Good publication houses for journals are IEEE, ACM. Selected journals of Springer and Elsevier are very good. Regard for a journal its impact index expressed by rates such as JCR. The higher the value, the more cited are these journal papers.
