Actually, I'm kind of in both camps. I prefer conforming clothes if I'm doing things like comics or graphic novels, but if I can take my time, I prefer dynamic dresses and skirts.

Since I'm still learning, I have a ways to go before i can do a real good conforming skirt. That's why if you'll notice, most of my freebies have been or included a conforming and dynamic item. Like this schoolgirl outfit for Miki4. The shirt, socks and shoes are conforming but the skirt is dynamic.
