Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
"User experience" means nothing without research of and validation by your own actual users! With, at the very least, usability testing of your site or application. In other words, the only general consensus to be had about what's good UX and what isn't comes from testing your web application with actual users in their actual environments.
Here's an example: Most designers and developers love the so-called hamburger icon for mobile website navigation because it's sparse and clean looking and doesn't take up much room, leaving space for other stuff in the UI. But it tests pretty poorly with actual users--in my own experience and that of many other who do usability testing on it. Many users have no clue what it is or what it does. Yet it shows up everywhere in design pattern libraries.
