Out of these denominations, which one has the most correct doctrine?

I don't know of any church that has a biblical doctrine, so I would have to say it is a tie between all seven you mention. The church of the Bible didn't pay huge amounts of money for buildings or ministers salaries, didn't advocate worshipping saints or Mary, believed in baptism (and yes, that means water), didn't believe in violence, met in homes, believed you could lose your salvation, didn't believe that Jesus and God were the same being (as Vot mentions above), etc.
