Apple never designed Pages to be a Word clone, and consequently, it handles lists differently. For instance, when you set up Apple Numbered lists with Tiered Numbers, when you press return from an initial entry, Pages yields this:
And you must tab the second item to trigger a tiered indent entry:
You must then visit the indent controls in the Pages list section and manually set the Indent distance to zero in order to align the tiered number beneath the first:
The tedium of this manual intervention will very quickly reverse productivity when using Pages instead of Word. The other factor is that Pages performs translation in opening and exporting Word content, and the result of that translation may not appear as you expect when viewed in Word. If your research report is being read as PDF, that may not be an issue, but if you are sharing it as a Word document with others reading it in Word, you would be advised to use Word to avoid document surprises.
