Compared to the 737's (I don't fly the regular A320/321's much) it is better, cabin is more silent, lighting is less easier on the eyes and the seats aren't 20 years old. The USB-power is greatly appreciated as well, having a fully charged phone on arrival shouldn't be the exception. I appreciate the new aircraft but since the WIFI isn't there yet, it is hardly solving any of the primary issues I have with SK.
