KeywordSpy is appropriate for most Internet Market research companies. I would not suggest it for a corporate marketing department unless it's a company with a very larger budget. This is also not a tool for small freelancers even though there is a free option, to get the best benefit of KeywordSpy it's best to use most of its features and options and this can get pricey.
Screaming Frog SEO Spider is well suited to auditing brand new websites, when you need a quick, holistic view of the websites technical issues. Its great for providing a top line view of a websites architecture, perhaps for a new business approach where you need to assess the scale of work to maintain a website. Its also a useful tool in situations where you might need to see whether a large scale change in the website has taken place, you can see word counts, pages and their https response codes. Screaming Frog may be less useful if you need an idea of the customer experience on a website, it doesn't really provide information that helps assess how fast a website loads, what issues might come up when trying to convert or faults with the payment process. Screaming Frog is largely a technical SEO focused tool, it also can't assess the quality of a websites, layout or the quality of the content used on the website. As mentioned, its niche, but very useful within that niche.
Requires Java. This isn't a huge deal as many computers already have it installed, but it's yet another 3rd party component.
The free version has a crawl limit of 500 pages per site. This is fine for smaller sites, but if you're running a big e-commerce site then you'll need to pay for Pro version.
The user interface isn't very pretty. This is an analytics tool so it doesn't really have to be, but it might be helpful for improving the overall user experience.
The tool has become integrated into our teams daily workings and I have yet to find a tool other than scremaing frog to replicate all of our use cases for it. It's a great tool and we're sticking with it
Easy for me to use because I have using the product for a long time and understand the ins and outs of it. If I was a newbie, I would be completely lost. It does take some prior knowledge to operate this software and understanding of what a crawl means
Screaming Frog is a relatively primitive system, and doesn't need to be supported by devs or other software. Screaming Frog does interface directly with some programs that are most needed (Google Analytics, Search Console, Page Speed Insights), so that's convenient. It isn't widely supported by other programs, but it also doesn't need to be.
Most SEO and market research tools offer what KeywordSpy has but are not as detailed and in one place. Consequently, where you can do everything at KeywordSpy, with other tools you find you have to purchase multiple tools or subscriptions from different providers which also don't integrate with each other. KeywordSpy makes your research easier and more efficient.
Screaming Frog SEO Spider is probably the best non-client facing SEO audit tool in terms of technical SEO. There are other tools on the market that do a more complete job of keyword tracking, competitive analysis, and backlink profiles...however, for analyzing the technical SEO health of any website, Screaming Frog is the best
