I assume that by "limited components and styling" is about the stats displayed by the analytics dashboard?
With UXWizz[0], I provide both: you get a UI with a bunch of useful pre-made graphs and data displayed by default, but you also have direct access to the MySQL database where the data is stored, so you can query for any specific data you want and get it in the format needed.
What I mean by this is that you've got a number of out-of the box graph types, with their own limitations. You can't access the code to actually change them.
Say you wanted to build Stripes new analytics [1] you'd need to build those yourself with all the subcomponents and layout within each component to have your own style and native feel. The percentage increase subcomponent alone for example will have a bunch of it's own properties (colour, size, shading, edges, race conditions, position within parent component, etc.) AND will have a specific data request to pull it back.
So I guess the question is, does it matter if it looks like your platform or not?
