I personally like the Trac5 S. I have admitetly not noticed some insane increase of kills over the normal Trac5 but I enjoy the utilities I can place on it.(Went from Granade launcher to Shotgun and now to smokelauncher(which be epic once they fix their smoke...) It is fun to be able to change the gun around so much, and it only costs 500 certs to get the Trac5 S.
Actually, considering pure battle characteristics, TRAC 5S is a downgrade from TRAC 5, afaik. It has longer reload or lower RoF, something like that.
