Yes: you get reliable source information and don’t get inaccurate summaries. E.g. last week I used Gemini to answer a plant biology question and got two contradictory answers based on minor variations in the wording because it incorrectly relied on blog spam over peer-reviewed articles for the first query.

The initial false answer was baldly asserted by the LLM without sources in the first two paragraphs but some of the phrasing it used was enough to locate the non-authoritative blog content it was apparently laundering. Had it accurately cited sources, it would’ve been easy to see that this random WordPress site saying X wasn’t as authoritative as the PubMed hits saying !X.
