I previously had a Samsung galaxy watch, but found it didn't really work well as anything other than a watch. Probably didn't help that I had an apple phone. Because I didn't use the (heavy) samsung very often the apple watch was a reluctant purchase, but from day one I have been really impressed with it. It works incredibly well, with seamless integration with my phone. It takes calls, well, operates spotify remotely, and I love the way it turns on siri simply by raising to watch to your mouth. The slick UI has made it one of my favorite gadgets, and it is in constant use.
