I think that standing H2H is a great benchmark. It's probably the first big benchmark for acro communities. For cheer communities, the corresponding benchmark would be a Liberty*, which is the basic entry-level trick for consideration as a professional-level performance, defining "proffesional-level" as "worth charging money for."
(*Liberty: Extended one-foot-in-two-hands overhead.)
Standing H2H is only impressive/intimidating to those who have been immersed in beginner-to-intermediate level acrobatic culture, though. In performance-level cultures it's entry-level, and is more likely to serve as a foundation for a more difficult trick.
AcroYoga/L-Basing and Sports Acro meet and balance, but how well they balance depends on the style being utilized.
In double-stunting, as well as most disciplines I've studied the would be categorized as "Sports Acro," the flyer's job is stay very, very still while the base does all of the balancing. The analogy I hear most often is "be like a ladder or a chair." A non-moving object is far easier to balance than an object that reacts to your attempts to balance it.
In AcroYoga, and in some disciplines of circus acrobatics, the flyer's job is to balance atop the base, who's mostly just trying to stay very still. They share the balance, effectively. For high-level standing tricks this is often the model. It doesn't work nearly as well for less-experienced standing flyers nor bases, however. But it's vital to AcroYoga. My stunt-trained flyers are always told to loosen up and not be so stiff, when they attempt to learn AcroYoga.
Additionally, there is very often a culture shock between various approaches to learning & teaching different styles. Professional-level coaches are typically akin to gymnastics coaches or sports coaches - they focus on fixing imperfect motion and position, attempting to train the student to perform the trick perfectly, rather than "hit the trick." Community-trained coaches are typically very warm and encouraging, checking in to make sure that the students are comfortable and relaxed. It's kind of more like guidance, rather than coaches. Coaches push students to the limits the coach knows that they can achieve, and progress is virtually always much faster. Some coaches push too fast or hard, resulting in injuries or near-injuries. Guidance Coaches, in my experience, tend to train students who are hesitant, nervous about new material, and slow to master skills.
It can be a culture shock to go from a warm-and-fuzzy AcroYoga environment, to a "Stay Tight!" barking Cheer Gym. Lots of recreational students do not like to be pushed, or made to fly past their comfort zones.
But I have observed that the Cheer Gym will reliably and quickly produce performance-level results, while the Recreational approach will take a remarkably long time to produce flyers, bases, mids and spotters that end up being sub-par, hesitant, and sloppy even though they took a much longer time to train.
