IMO, it's exactly the same process, just using different tools.
One creator can go to Wikipedia and look for the "Stained Glass" article.
Other creator can go to Pinterest and search for pictures tagged with "Stained Glass".
A third one can go to reddit.com/r/StainedGlass (yes, it's a real subreddit) and sort the posts with the most voted from all times to see what's going on.
A fourth one can go to the nearest Cathedral, if he's lucky enough to live nearby one, and take a look at the beautiful artworks there.
And, finally, a fifth one can go to ChatGPT ask for buildings with Stained Glass.
Which tool is the best? There's no such thing. To each their own.
Exactly my thoughts as well!
