I prefer traditional server side frameworks precisely because they have a rigid pattern of doing something. And also because they have been around for a while. I don't get excited about learning a new frontend framework because I'm fairly certain it won't allow me to do something new. It may be more convenient in terms of syntax or have fewer client side code being shipped, but it doesn't enable me to do something in terms of functionality I couldn't already do. I would prefer pick one framework and get better at it, rather than learn the templating language of 5 frontend frameworks.
