Anass,

That depends on a range of factors. For instance, best to target the same journal if it is one of the better quality, established journals in your discipline, where you may have links to the editors/editorial board, and your research is current and topical for that journal. If you have previous articles published in that journal and have had good reviewer feedback and good overall experiences, then that may motivate you to continue submitting. Plus you get used to the formatting and style that the journals tend to favour. For instance, personally, I have submitted dozens of articles to a few of my favoured journals and had them accepted (they are the Journal of Advanced Nursing and the Journal of Clinical Nursing). I know the editors well and I have a long association with the journals.

On the other hand, 'a change is as good as a rest'. I target other journals for a range of reasons i.e. not all my research is nursing-specific, my co-researchers may favour other journals and have their own associations with them, I may have been invited by other journals, sometimes it is good to 'have new challenges' etc.

I would argue that a mix of approach is best. I wouldn't want to restrict myself to only publish in certain journals - but it looks good on your CV if you have a number of publications in established, proven journals.

I think it is better to publish in different journals because publishing in the same journal may be seen due to a special relationship with the journal, given that we become known by the editor, instead of regarding the quality of the paper.
