Bytecoin has been premined 82%.

Boolberry has been hugely instamined probably over 20% with 1 guy making 2,000 Boolberry per day off his private gpu miner as of right now, since Boolberry uses Wild Keccak instead of Cryptonight algorithm. He was making 7,000 boolberry per day for a long time before the difficulty increased, and Boolberry only has 18million total coins. I'd say that 1 guy owns more than 20% of all Boolberries as of right now. Boolberry has both a guy with a private gpu miner that gets 2,000 boolberry per day as of right now, As well as botnets. I wouldnt be suprised if Boolberry has over a 60% instamine.

Monero is the only fairly launched cryptonote coin with a large very active dev team..

Monero wins hands down.
