The better SSD: Plextor S2G 128GB M.2 px-128s2g VS. WD Green 120GB wds120g1g0b VS. Kingston 120GB G2 sm2280s3g2/120g

Which one would you choose?
I know the WD Green is DRAM-less, but not much about the Plextor and Kingston.
Please do not recommend higher capacities or other SSDs. These are in the price range of the friend I am advising and available. This will be a boot drive and his laptop also has an HDD for media storage.
 
Solution
The px-128s2g looks like the best bang for the buck. I've had good success with the couple plextor SSDs I've used personally, and that model has great read/write performance for a 128GB, especially with read IOPS where you'll actually feel the performance for an OS SSD.
