I stumbled onto Vision after evaluating numerous other brokers. It was mostly an accident rather than a sales pitch... Vision happened to have a technology platform (Ninja + Rithmic) that I relied on for my black-box trading.
But after 3 months with Vision, I'm a fan. It's surprising Vision doesn't get more attention, since they're a larger operation, and have more in customer segregated funds than Advantage or even IB.
The people I've dealt with at Vision are incredibly competent, ranging from back-office operations when clearing pit-trades, to the platform guys supporting their trading applications. Their web/account portal is also world-class, far better than any of the other futures brokers that I've seen.
The rates I'm getting are reasonable, albeit not as stripped down as some discount brokers may be. But I personally believe the service and reliability makes it worthwhile.
My only slight warning is that TT, CQG, and Pats are not available as trading software/front-end. But for those of you using ZenFire, then you're not losing anything by going with Vision.
Vision also has a reputation for aggressively selling CTAs through their IBs... which may be a consideration for some considering that route in the future. John W "Red Sox" Henry is running a program through them, in fact.
Of course, a lot of your personal experience will also depend on the actual salesperson or IB you sign up through... so choose carefully.
