As everything it has some downsides. Their mapkeys are amazing, but it has a lot of limitations when you want to write the code by yourself to change the variables, plus you need an extra license to reach the real power of their parametrics which shouldn't be this way.
The family tables have no finding function, making you go through an excell sheet to find your components or scroll around through one hundren components list PLUS dimensions (or even more).
When you are assembling the only thing that is going to be a strugle is when you apply degrees as a restriction to have a components with different directions, their angles are really bad and moves wrong continuously
