Which one should I go for a Iommi SG Epiphone or a Epiphone G400 with EMG's ?

Which would have the better sound I've heard the Iommi has sick sounding pickups but so would the EMG's, which would be preferable for thrash metal sound Metallica/Slayer and old Sabbath songs ?
the Iommi one i think is better. it has his very good heavy sound, i dont like the G-400 at all for some reason.
The iommi one might be better quality. But its kinda pricey and for some more you could get a gibson instead. But the g400 plus new pickups is a good idea. I'm gonna get a new bridge pickup soon hopefully, but most likely not any EMG's. :p
