It's a great tool for front end testing. However, it's limited with some newer stuff - shadow DOM objects are meant to be supported since January but in reality it's...difficult. However, the way it interfaces with browsers IMHO is preferable to say, CodedUI, which takes control of the mouse and keyboard to execute tests. Saying that, in Java/C#, Selenium is still easily my preferred tool, and the demand from companies/recruiters (I'm switching contracts at present) seems to indicate it's still very much the tool.
