Never goes force against force, and works in an armored or unarmored context, against single opponent or multiple opponents. Gives greater extension for a wider array of techniques, plus extensive level changes, and even utilization of one-legged stances in proper context.
Best of all—its the only sword art I've learned that formalizes edge preservation, when taught correctly, by always aspiring to counter/control the opponents blade with the flat of the blade. Edge to edge contact will only occur in blocks, where blocks are considered a failure—the inability to counter (parry) and riposte. Many wudang sword are only meant to be sharpened for the last couple inches.
(I've seen HEMA longsword parry/ripostes that look quit similar to wudang techniques, since the tool and context guides the technique. You may also want to check out this choreography, where one combatant takes up a Chinese longsword.)
Since Wudang, like tai chi, is ultimately a system of movement, as opposed to a given set of forms or techniques, I find the training to be more optimal. It does include practice of forms, but with the caveat that all movement is generated by the waist. This allows me to work out with a 3.5 lb blade for hours at a time, without exhaustion, and no tendon damage to the wrist. The arms and legs merely follow the waist, and the arms are extended, circular (joints sunk) and relaxed. The framework this creates is very firm. Grip is strong/firm but not tight.
The practice of forms is also rewarding. Aesthetically pleasing, strengthens the core profoundly, and a high level of technique is so difficult to achieve, no intellectually honest practitioner ever considers themselves to have fully mastered anything. My technique at 50 is significantly better than at 20 or 30 or 40.
A caution is that many modern wudang practitionars seem to conflating armored combat with unarmored, via protective equipment in a sport analog, which seems to incentivize unsafe strategies. By unsafe I mean striking without clear advantage, which leaves the attacker exposed, and can easily lead to death in a real sword fight. (Academic, however, as no one really swordfights anymore.)
Wudang also adapts to modern fencing (duelling/unarmored combat) via Dan Pai, which allows for lighter blades. There you will see significantly more point work, like western rapier, and an emphasis on wrist cuts because Chinese swords do not employ basket hilts, which can inhibit versatility.
Heavier wudang blade weights seem to be for the purpose of cleaving, where the combatant need to be able to guarantee felling an opponent with a single stroke, and cannot depend on thrusts because multiple attacker situations is assumed. Because Daoist swordsmen and swordswomen travelled extensively, the blades had to be durable.
