I like Shimano hubs because they're easy to work on and easy to source any necessary parts. The weak link on rear hubs is the freehub body. If you happen to trash out a Shimano freehub body (rare) you can just plug in a new one. For me the Ultegra level is the sweet spot but everybody draws that line differently.
There are hubs that are lighter in weight and are still durable, but they tend to cost a lot more.
