I was wondering what others think of the two ecn's. The only thing that I can see as the major difference between the two is Brut being part of super montage? They both have connectivity to different sources of liquidity: market makers, other ECN's. The only difference I can see is super montage participation or not. I actually like Brut instead but I wanted to see what others think of the speed when stocks start to move very quickly and you need to lift an offer or hit a bid.
