I've been a Marvel Age completist thus far, but I probably won't continue with Rawhide Kid and Sgt. Fury.  I never thought I'd buy all those volumes with Conway material, but once I started, I was kind of 'forced' to continue, and the material is still of value to me from a continuity perspective.

I tried to like GA and AA, but just couldn't get into the few volumes that I bought (which include GA Marvel v.1-5, AE Menace, and AE Venus v.1, and a few others).  Nevertheless, they were interesting enough that I don't regret getting them.

RK and Sgt. Fury are not completely without merit, but I have a hard time seeing going further with each, as the stories kind of all become the same at some point.  But who knows, I might break down again due to my mild ocd element, if and when the choice arises.
