Sola scriptura has had many years, and many practitioners, to “progress” in countless contradictory directions especially in the USA. Its flaws are now obvious to more people.
The Trad movement, or Solo Traditio, is much newer, with fewer practitioners. It sounds safer, more Catholic, less wiggle room. But once you get away from the current Magisterium, there’s a tendency to make yourself the magisterium.
Thus, the Trads will increasingly contradict not only the Magisterium but each other. It’s just at an earlier stage than Sola Scriptura.
