the cards are basically the same reference design from nvidia, the vendors add their own cooling options ram sizes and software. in my shop, i like the build quality of evga over the others. i have 8 different evga, 2 msi and 2 pny cards. with the pny being my least favourite. in your list, i have 4 of the evga 3gb cards with the acx cooler, 2 in my main cc pc, and very happy with the perfomance!
