The most important part is knowing how to use that weapon... A noob handling an AGS, could loose to a dude with a dragon long (i once killed an AGSer by using full verac, he was 20 cb lvls higher.)
Still God Swords provide an excellent strength bonus, which really helps wipping hp.
As to Dragon Claws... 2 Options: Buy them as fast as possible, pk with them and then sell them.
Or wait for a nerf, then buy them.
In my opinion, full verac's combined with sgs is the combo that works best for me in PvP (100m+ done in my pker)
