Using both MX2 n CC5 wid d same size as urs on 2 Corollas now. CC5 if not mistaken is about 2 or 3 yrs in d market, so i think u got it mixed up wit d CC1 predecessor which is still fitted to some new Nissans.

Between tis 2, CC5 is a lot softer n comfier than d XM2. U can chk out my own findings here

No chance to test out d MC5 coz d shop didnt hv my size but from d looks of its grooves, I wont b surprised if it performs a bit better than d ol XM1.
