I can relate to what you are saying. I have seen numerous Wing Tsun classes and if I attended I would feel the same way. It's not just about finding the right art it is about finding the right teacher as well. I preferred traditional Wing Chun over modified Wing Tsun for numerous reasons mainly the footwork. If your on a train track and the train is coming you can pivot all day long but in the end the train is going to crush you! Traditional Wing Chun uses footwork that gets you off the line of force. In my old school we had open fight nights so martial arts from all styles could come test skills. It was loads of fun and there was something I constantly noticed. Everyone outside of our school left shaking their head saying we got to fix something and fast. We all left saying glad I know Wing Chun!
