Perhaps, but learners that are good in the current system will do well regardless imo. They are good at self directed, isolated learning which I think is the minority.
Those same 'independent' learners end up carrying the groups they're placed in. In the best case they're essentially drafted as unpaid tutors for the rest of the group, but often they end doing most of the work themselves while sharing the credit with the others. In either case they end up overworked, but particularly in the later case it becomes a system for gaming statistics to make the whole class look like it's performing better than it really is. Teachers like setting up this kind of system when their compensation/advancement is tied to student performance, a manifestation of Goodhart's Law. The sort of equality that you can achieve by giving student the average grade of a group is just a trick with numbers. Why not grade the whole class as one single group? Average every test score together and give every student that average score. Now you have excellent equality as the whole class performs adequately... but only on paper.
Anyway, there's no "one size fits all" in education, any scheme will favor some students more than others.
