I think the only things these plots tell you is that on average the
top system has a larger radius of gyration than the bottom, and that
the RoG of the starting conformation for the bottom system was closer
to its final value than the top system. It could be that both will
eventually stabilize to different values, or 10 ns from now maybe the
RoG of the bottom system will suddenly spike. In my opinion there's
just too little information at this point to say that either model is
stable. One way to start addressing this would be to start another
independent simulation for each system, using different initial
velocities (and ideally different starting coordinates). Then you can
start to get some idea of the variance in each individual model, which
will help you when you compare the different models to each other.
