I can understand that some people think Xg can be boring, but it is a fairly useful analysis tool. After a match, most supporters talk about who had the most shots on goal, and who had the biggest chances. What Xg does is quantify just that on the basis of a large amount of data.
Furthermore, you adjust for distance, angle, which body part you use to finish with on the goal, etc. The latest model also takes into account the player's skills. There are a number of variables you adjust for in the model. Then it's just about probabilities, which in itself can be difficult enough.
Still, the Xg models are far more reliable than variables such as shots, shots on target, etc. No models are perfect, but it is an upgrade from previous models. I think all clubs use the model in one form or another, but there are many different Xg models. So if you cling to older stats like shots on goal, and make fun of Xg, you should update your knowledge.
However, I think, if I remember correctly, shots on target outperformed an Xg model in Scotland a couple of years ago, but in general the Xg model is far more reliable.
