I agree with both your points. Wikipedia is extremely useful because it's generally very good - and it's also not perfect.

I'll add I don't think it can be any closer to "perfect" than it is because the same fundamental traits which lead to its imperfections also enable its unique value - like speed, breadth, depth and broad perspectives. The only areas where it might very occasionally not be ideal tend to be contentious political and culture war topics or newer niche articles with low traffic. Basically topics where some people care too much and those where not enough people care at all.

But this isn't as big a downside as it might be because anyone can look at an article's talk page and edit history and immediately see if it's a contentiously divisive topic or, on the other end of the spectrum, see when there's been little to no discussion.
