Form II
The ultimate refinement of lightsaber-to-lightsaber combat became Form II, advancing the precision of blade manipulation to its finest possible degree and producing the greatest dueling masters the galaxy has ever seen.
Today Form II is an archaism studied by almost no one in the Jedi Order, because it is not relevant to current tactical situations, in which Jedi enemies rarely fight with lightsabers. Even with the resurgence of the Sith, confrontation of an enemy with a lightsaber is an exceedingly rare prospect for a Jedi, so they continue to focus on more practical Forms. Sith expecting to battle lightsaber-wielding Jedi, however, find Form II a powerful technique.
Form VII
Only high-level masters of multiple Forms can achieve and control the ultimate descipline known as Form VII. This is the most difficult and demanding of all Forms, but it can eventually lead to fantastic power and skill. Form VII employs bold, direct movements, more open and kinetic than Form V but not so elaborate in appearance as Form IV. In addition to very advanced Force-assisted jumps and movements, Form VII tactics overwhelm opponents with seemingly unconnected staccato sequences, making the Form highly unpredictable in battle. This trait makes for a much more difficult execution than the graceful, linked move sequences of Form IV. Form VII requires the intensity of Form V, but much greater energy since that focus is wielded more broadly. Form VII draws upon a deeper well of emotion than even Form V, yet masters it more fully. The outward bearing of a Form VII practitioner is one of calm, but the inner pressure verges on explosion. Form VII is still under development since so few can achieve the necessary mastery to advance the art.
Source: Author Dr. David West Reynolds and fencer Jack "Stelen" Bobo derived the "in universe" principles of lightsaber combat based on the action that appears in all five Star Wars films to date. An importance notice to the reader: these Jedi histories are not stunt choreographies nor intructions from Episodes I and II Stunt Coordinator Nick Gillard, who developed the exciting sequences we see on screen. Do not attempt fencing without proper safety precautions and training.

Really, it isn't in the original author's intent of the form, and while I remember Shatterpoint the novel all but fellating the form, it was the Shatterpoint technique that made Vaapad more dangerous than just any other form, along with his borderline darkside philosophy.
Yes, Mace is likely very comparable to Dooku for sheer skill and ability, and a battle between them would be intense, but Vaapad itself isn't superior to Makashi. Dooku would WTFrape any other practitioner of the form with relative ease.
