White Ensign Models went out of business for a while, but seem to be back. They were a primary source for Royal Navy and other European subjects. Their paint line is Colourcoats, which is still available. Since you like RN subjects, you should get to know that part of the hobby.
Yes their products are good. Fair question, but as a new modeler to ships learn all you can to make PE work for you. It's important in steel navy modeling.
Other good sources are Gold Medal Models and Toms Model Works.
