Whilist I admire Boolberry and cryptozoidberg (Generally I admire any talented developer), the reasons for XMR being larger is because the blockchain scaling is not a problem at all in my opinion. Even Bitcoin at 20 gb blockchain is nothing, Gavin is already trying to solve this with Bitcoin and any improvement could be forked over to CryptoNote. The whole scaling problem will be solved one way or another in the future by some genius dev I am not the slightest worried it will be a problem.

XMR dev team is larger than BBR, the dev team consist of atleast 10+ different developers while Boolberry have one dedicated one named cryptozoidberg, while he should have cred for his efforts, I personally believe XMR is the better investment here. Purely speaking from an investment perspective I think any change that would be made to Boolberry for the better could be ported over to XMR easily.

Monero have a better branding name, bigger following and a seems to be the winner the marked picked in this race for anonymity.
It is clearly the winner among the CryptoNote coins.
