@ashleykaryl, thank you for mentioning circleCMS. In a first version, adding/managing pages will not be possible, but this is planned for a later version.
My opinion:
I like the faster reaction time of Blocs, Rapidweaver is really very slow on my 15" late 2016 Macbook Pro. Rapidweaver has until now the better API, but Norm ( The main developer behind Blocs) is working on it, to improve it. If enough people are asking a thing, Norm is implementing it. It is at least how I perceived it.
Rapidweaver has a really good eco system with many developers, so as website creator, there exists more out of the box solutions. Personally I prefer Blocs because it makes more fun working with it, and can manage fonts better out of the box. for me, fonts are a main part of any design.
