I have used both, and did not like the EverCreme at all. I probably would have put up with the smell if it worked well on my hair (the sacrifices we make for beauty!), but it left me with frizzy, limp, greasy-looking curls.
OTOH, the EverCurl clicked for me immediately. Fourth day in a row, and I have bouncy, frizz-free curls without using a rinse-out or leave-in.
YMMV, of course. A lot of curlies loved the EverCreme CC, including the scent. (From what I've read, the entire L'Oreal Ever line contains strongly scented products, so be warned if you're sensitive to perfumes.)
I have a sample set of the L'Oreal EverCreme if anyone wants it (poo, condish and masque). No CC, but you can still get an idea of whether the line is for you. Drop me a PM if interested.
