Cons
Con Theme inheritance doesn't seem to be a priority
There have been endless discussions for years but theme inheritance still doesn't seem to be a thing. You can "inherit" from the simple theme so you don't have to have all the required files in your theme, but that's as far as it goes.
Con Not as powerful as other more popular site generators
Con A little bit slower than some of its competitors
Con Documentation can be hard to navigate
Especially for someone new to Assemble, it can be difficult to find what you're looking for in the documentation.
