Not debating one's preference. Just offering a point of view for those the flaws that you have highlighted that they are correctable if someone has the skills. Another reason for slow load times is the number of objects a page layout calls. On pages with fewer blocks calling fewer objects the pages load relative quickly. On pages with many blocks, calling many objects the load time is slow. A developer with strong skills is capable of reducing the load times considerably by editing and restructuring how UNA loads the pages. For the cost of the license UNA is an incredible value. And their support is mostly excellent, especially @LeonidS My biggest critique is they put the horse in front of the cart by announcing big advancements and then we wait a year or two. A great example outside of NEO is the stories module. They announce it is done and then never deploy. They are not perfect but I am thankful for their product.
