Quartile Scores (Q1-Q4) or Impact Factor (IF), which one is more important?

Journal Citation Ranking and Quartile Scores (Q1-Q4):
Based on Impact Factor (IF) data, the Journal Citation Reports published by Thomson Reuters provides yearly rankings of science and social science journals, in the subject categories relevant for the journal.
Quartile rankings are therefore derived for each journal in each of its subject categories according to which quartile of the IF distribution the journal occupies for that subject category. Q1 denotes the top 25% of the IF distribution, Q2 for middle-high position (between top 50% and top 25%), Q3 middle-low position (top 75% to top 50%), and Q4 the lowest position (bottom 25% of the IF distribution)

Hello,
"Q" and "IF' are the two different assessment of the any Journal validity, but I think high "IF" ISI journsls are good one.
Thanks,
I also agree with Dr. Shahab, I think Quartile Scores is more important than Impact Factor
In my opinion Quartile Scores is more important than IF because it reflects the quality of research published in the journal for more clarification check the link below:

I think the problem you address should be valualbe. Yes, if it is in Q1 ranked journal, it will be better.
In my opinion the Quartile value has the advantage that it is typically already related to a defined field and gives in this way a measure which is relevant for the desired readership whereas IF can be understood completely different by people with different backgrounds. For some people a paper with IF of 3 might be highly attractive there are other research areas where settled scientist would not aim for Journal below 8.
Therefore IF gives an overall ranking but for a decision it requires an overview of the relevant field which is in the Quartile values already included.
The Journal Impact Factor quartile is the quotient of a journal’s rank in category (X) and the total number of journals in the category (Y), so that (X / Y) = Percentile Rank Z.
Q1: 0.0 < Z ≤ 0.25 Q2: 0.25 < Z ≤ 0.5 Q3: 0.5 < Z ≤ 0.75 Q4: 0.75 < Z

Another important information on each journal can be obtained from this famous website:
https://www.scopus.com/
Here you can find the percentile for the journal compared with the other journals in the same field of study. For example, a journal has ranking 154/204 in some field, means its percentile is 24th. In other words, this journal is better than 24% of other journals in the same field.
