VueJS seems to be the easiest DX to get going in a sense that it has the least amount of files and can be researched very easily. The components can be understood without a large amount of knowledge for that same reason which makes customizing it much easier and more convenient.
Due to VueJS being very simple to operate with this is what I would have to with. It requires very little which would allow for a quick app to lay some groundwork out. If I were to dive in and make something large in scale I would then use Angular or React due to their communities for help and future progress.
