silicon power p32a80

I don't know which to choose... By comparing both 1TB, XPG SX8200 Pro = $203 , SP P32A80 = $145. R/W XPG = 3500/3000 , SP = 3200/3000 I don't know which is better for performance (not considering R/W speed as both similar), durability and quality. Any experienced or who are using these M.2...
