One big difference is the Emporio's have a butt maximizer panel design. People teased me for that. At the time I didn't really distinguish all the small details. I just wanted something with a bold logo around my waist to enhance my abs. The butt maximizer it non effective on me as I do plenty of squats and other
exercises for the legs. I'm pretty thick and toned so the maximizer qualities seemed a bit artificial on me. I wore them several times to stretch them so they fit my body better. In the beginning it was as if the underwear was pushing into my taint area.
I wanted it more stretched on my ass not lifting and separating. It looked funny and wasn't in place like it should be. Either it didn't cover my hips or I pulled it up to high and I had a weird camel package. In time I got them to behave properly and when I did they contoured perfectly. The CK steel fit right out of the box and seem more reliable
