Urgh, what? S doesn't even break a sweat on V2. Driger V2 is commonly known as the best uncustomized plastics, though S is certainly no slouch. Get Driger F if you have Dranzer S, Wolborg 2, Master/Kid Dragoon, and a Wide Defense- Upper Dragoon+Wide Defense+Right SG Free Shaft Version (Full Auto Clutch Shaft)+Defense Grip Base 2 is a competitive spin-stealing-upper-attack combo.
G's main selling point is the AR, Triple Tiger. It is an incredibly versatile Attack Part, and on a good attack base (DGB Attack Mode, CGB (native tip), GCB Tip on WB2 casings and Defense Grip Base 2) paired with Ten Wide or Wide Defense (Wide Survivor for the GCB tip setup), Survivor Ring (on CGB), a Right SG (Neo or not) it is a fearsome attacker. In fact Triple Tiger is so good, even with that tall engine gear and blade base Driger G is a decent out of the box beyblade, and one of the best cheap beyblades on the market competitively.
S does well uncustomized, but if you want more get a Takara/Sonokong Metal Driger (avoid Hasbro, they don't have HMC) to get a Ten Heavy and HMC, and probably something cheap with Neo Right Casings to make Tiger Defenser+Ten Heavy+ Neo Right SG HMC+ Metal Change Base which is a good compact. Tiger Defenser is also a good AR for defense/zombies/compacts.
F has Full Auto Clutch Shaft, which is realllyyyy fast especially on FACB. Cross Fang (AR)is fragile though, and FACB is useless on anywhere but practicing with FAC Shaft. The combination on the first paragrafh is one of the best possible with FAC Shaft but i'm interested what it does on Cross Griffon+Ten Wide+FAC Shaft (Free Shaft Ver Casings, right spin)+Defense Grip Base 2 (smash setup)
So if you can, get S and G, and unless you have Dranzer S, Wolborg 2, Master/Kid Dragoon leave F alone. I'd admit F is rather easy to find though.
EDIT: Whoops, got quad-beaten here lol.
Beywiki is incorrect for some of the articles (sadly, Driger V2 is among them) on plastic beys. I've heard V2 sweeping entire tourneys uncustomized (ask th!nk if you can, he lost to one), and no, S doesn't do as well as V2 uncustomized. S can defeat many beys uncustomized, but it's nowhere near as good (or annoying if you're fighting it) as Driger V2.
