In my opinion the ETC hardfork was much more justified than the current BCC split. BCC feels more like a cash grab to me. Not that that ever stopped an alt from growing.
The thing is, ETC stayed under $1 for a good long while, then rocketed up to $20 and beyond for no apparent reason. Most players had expected it simply to fade and go away, it would seem, but it's still going relatively strong. Who's to say that BCC won't follow a similar path? Indeed, maybe BCC will confound all expectations and become the dominant coin.
ETC may have grown from a fiat perspective, but relative to ETH it has rather stagnated. BCC may also see huge fiat push, but that doesn't count much if BCC falls relative to BTC.
