I think the "beginner's level" idea is more based on marketing than the sonic capabilities of these drums. They were engineered to sell at a lower price but the Club Dates were the same as the Classics except for the center lugs and the Acrolite used the same aluminum shell as the Supra. Being lower priced options they primarily appealed to students and drummers just starting out, but they weren't lower quality drums. If you can get past the idea of them being "beginner drums" they can work just as well for you as any of the other Ludwigs of the day. Same with the Standard line drums...they all have the same 3 ply shells or aluminum goodness, all made in the same plant by the same people to the same production standards.
I have 4 or 5 Acros (and a couple of Club Dates) and I love then all.
