Have been studying a number of Technical/Side Mount escapes, and dismissed a few in favor of others because they required more movement for essentially the same result.
Less movement means less energy output, and counter opportunity. =)
Another small distinction one can make here is two approaches may have the same number of steps, but the ground covered in each step can be vastly different…
