i have the opposite experience as i've found it to mess up a lot to the point that I can't trust the AI Overview answer at all. I've seen it be confidently wrong too many times and now the trust factor just isn't there.
I've found that the AI overview is usually right but confidently wrong enough of the time that I don't trust it. The interface that you get with the 'AI Mode' button (which I assume is just Gemini with very low compute settings), however, is usually pretty solid for well-documented queries.
