I am quite proficient with dynamic cloth, but I don't use it as much because it takes longer to deal with it. Like MissB, I reserve it to cases where it's better suited for, like with very loose cloth, capes, skirts and long dresses. For everything else, namely outfits tight to the body, conforming does the job and it's much easier to deal with.
In Poser, the default parameters for dynamic cloth will work well with most cases, but things can be unpredictable. That's because dynamic simulations depend a lot on vertex density, so if we apply a morph that changes the cloth shape, the vertex density will change, and so will the simulation results. In addition, low poly outfits may be fast to simulate, but may not bend well, while heavier meshes will bend better, but will slow down the simulation. The fitting must be perfect, since any intersection with the body might result into cloth exploding. The mesh must be clean and well built, or else the simulation may crash or have unexpected malfunctions. For those reasons, it's best using cloth that was meant to be dynamic.
I could write a book on the aspects that affect dynamic cloth, but you get the point. Once you understand the multitude of parameters, things start making more sense, but the results are always unpredictable and will require some fiddling and experimentation. If you just want a quick render, then dynamic cloth may not be for you. It may be a bit frustrating at first, but there are specific cases where dynamic cloth is your best bet.
