Netlify CMS is well suited when you have very less frequent updates to your content, maybe once a day and very few people need to access your data. You can connect it to Netlify, GitHub, or any platform and have multiple people access it and do as many updates as you wish, but the process is not well-defined and you need to build your own system for that. It is well suited for projects you need to pull off with very low cost, it is essentially free as the software is open source and free to use, and all you need to do is set up your schema correctly and find a deployment pipeline where you can build your static site/API to redeploy whenever the content changes. I personally used a GitHub Login -> Netlify CMS -> next app consumer of content -> GitHub pipelines to run next SSG -> GitHub Pages to deploy the built static site. It might not be appropriate for large teams where users themselves need no-code tools to modify the schema of the content.
As already mentioned, migrating websites from Adobe Business Catalyst, or any other platform is a strength. Using the Siteglide CLI, websites can be migrated as a static site to Siteglide, thus greatly reducing the amount of work necessary for the migration. Also, as long as developers are acquainted with HTML, CSS, Liquid, and Javascript, building sites with Siteglide can be done rapidly using their Siteglide Studio site builder. One of the additional strengths of Siteglide is Webapps. These can be easily used to provide the display and manipulation of dynamic data. The site can be designed so that users can change information without knowing anything about the underlying code. It allows a form-driven way to update site pages.
Billing plans occasionally cost more than competition, mainly because of the way Platform OS works
"Drag and Drop" website building and maintenance could be improved in order to compete with other site-builders. Less reliance on knowing HTML, CSS, Liquid, Javascript, etc. would be a good direction to go in the future.
There could be an improvement for "non-programmers" and drag and drop editing. However, Siteglide's target market of website development agencies is well served and a great fit. Sites can be migrated from other platforms quickly and easily. New responsive websites can be developed quickly using Siteglide Studio and then robust functionality can be built out quickly and reliably. There is a wide range of features included in Siteglide and more features and upgrades are being rapidly added. The environment is built on a stable and performance-oriented platform. This allows agencies to provide excellent service on a worldwide basis.
We really can't compare it to full-fledged CMS software, like WordPress, which has a lot of community and support with widgets, plugins, and whatnot. It's not built for that, but you can compare it to Contentful, Ghost, Strapi, etc., which provide similar functionality to a headless CMS with custom schema options, but even among them, it still lacks a lot of functionality, ease of use, and support. But Netlify CMS pros would be of the opinion that compared to other platforms where most schemas need to use their own tools and frameworks, it's very cost-effective. Something new called TinaCMS has come up to compete with Netlify CMS by covering most of its shortcomings, but it's something new being built by the same team that built Forestry CMS and comes with many modern features, yet currently only supports NextJS SSG.
Siteglide knocks the socks off Duda in terms functionality, it's eCommerce isn't a match for Shopify (yet) but it's got a lot more flexibility and functionality than Shopify which comes up short if businesses want to do more than sell products...and versus WordPress, well, it's just much more professional and doesn't fall on its arse.
