A "faster" drawing time is dependent on you alone. As mentioned earlier in this thread, cintiq, intuos, and surface are only tools. You can get faster on your current tablet just by becoming more familiar with its shortcuts and changing your style around a bit. Some people do think they are faster on the cintiq but those reasons are more ergonomic. Personally, I have a really hard time with the slant. To avoid glare I have to bend over it like the hunchback and that really slows down my drawing (not to mention, it hurts). After I got used to disconnecting my hand and eye years ago on the intuos, I drew just as fast on the intuos as I do on paper.
