Ranked by number of bottoms bred
Please Note: While (at least for some guys) there's definitely an eroticly dangerous aspect to the idea of a poz top cumming inside of a bottom, in most cases the danger is imaginary. Since at least 2008, when "The Swiss Statement" came out, we've known that it is impossible for someone who is on anti-retroviral treatment with an undetectable viral load to transmit HIV. In fact further studies have shown that HIV+ persons are unlikely to transmit the virus if their viral load is under 2000 (which is well above 'undetectable'). Hence these poz bareback tops have most likely not put the bottoms they've fucked at risk of HIV – even if the bottom got the top's cum in his ass. For more information on why this is true, google "TasP – Treatment As Prevention".
