Technically it was not. It was an emotional attachment. Although software selection for C64 was about 1,000,000,000x better. 
i loved both machines. we used the C64 for a very long time indeed because of the games, but the IIgs was much more useful in terms of software that one actually, er, uses. and the system software was like a mini-mac. it was terrific.
i highly recommend getting a IIgs if the OP can find one in good condition and can afford it.
