In Reebok Edge 2.0, size 52 fits me perfect. For the Adidas, I tried on a 52 and 54. If I was going to buy one, it would be the 54 (prefer a little more). Downside, sleeves and body length were longer than the Edge 2.0
Overall material felt more like a Reebok premier to me. I do not own any WCoH authentics to compare.
Fight strap as mentioned in other posts isn't great. Both white and black jerseys appear to have the same strap: white strap sewn on to white twill.
Customization is again comparable to Reebok premier. I would buy blank and send out more for accurate, mainly for higher quality materials.
Didn't look at the crest too closely. 44 was just on the front of the rack which is why it was in my picture.
