When looking at impact factor, ResearchGate is not a good source. In fact, although I’m on ResearchGate I found already quite some flaws in their system and the information they give.
If you look at the golden standard we use (i.e. the Web of knowledge), there’s no reference to either journal. The impact factors we take into account here, are those reported by Web of Knowledge. If a journal is not mentioned there, it’s not considered a scientific peer-reviewed journal.
