I actually disagree with the general sentiment here. It is true that you are unlikely to find domains worth $1000s when scraping in 2024 but if you want domains with links from your competitor, you aren't finding that on an auction site or dropping domain list. You can target general niche with these sites but finding domains that have links within your niche takes a lot more work than just searching for a given keyword or crawling a site.
If I were buying and selling domains or looking for any strong domain to build a website on, then auctions and dropping domains is a good place to start as you can find the better domains out of everything coming available there. However, if you are in a tough niche and want a specific type of domain, perhaps with links from a competitor or authority, then scraping the site is the most reliable method (or using a host of third party services to get the outbound links, split to domains, check for availability for example).
I suppose the decision is to either spend more for a, generally, more powerful domain from auction that is in a similar general niche to yours, or get a very cheap expired domain with links from the big guys in your niche. The latter will likely have much lower stats but will be way more relevant. I can't say the latter is necessarily better but you can get many expired domains for the price of a single auction domain as well and they could be really targeted to your niche.
