In short, the main difference is the also the main reason why Bubble users look elsewhere: scalability. Bubble is great
when it comes to eye-candy: beautiful interfaces are easy to build. However, as soon as the app reaches scalability stage, things start to slow down. Directual, on the other hand, excels at scalability without losing in the looks department either, especially with some fine-tuning. On top of that, Directual and Bubble
make quite the power couple, as they can be integrated together!
