4x is the max usefull zoom factor for airsoft when you want to shoot.
2x would be good if you have an AEG at 400fps. 4x would be a bit more suitable for sniper that need to do more recon and surveillance. There is not much differences bewetting the two factors, but for fast shooting, 2x would be best.
