I have some experience with Angular 1.x, and right now I am building a stack for couple of new projects.
... but I found https://mdbootstrap.com/angular/, which looks like some kind of combination of Bootstrap and Material Design which suppose to work as well with latest Angular.
I am confused and I am not sure what are main differences between those two approaches.
Material Angular allows you to use Flex Layout which gives you a responsive grid if you spend the time to learn it.
I've been using it for multiple projects and it is great.
