Have owned both boats. Both boats handle big water well.
I feel that the WX2190 is better in big water because of the hull design and deeper sides. The Skeeter pushes the spray out further and the windshield is taller, so you get less water coming back at you when running in the rough stuff.
I would test drive and crawl through every boat in the size that you are considering and let that help you make the decision.
I agree with riverrookie in that dealer that you purchase from is very important. When looking last year SBC put a WX2060 and a WX2190 side by side in the heated bays so that I could climb from one boat to the other to compare and let us test drive them as well. Never offered that anywhere else.
