So it sounds like you are locked into IB and just want to know the plus/minuses?
Lots of good and bad with them.
Since you mention you are trading 1256 contracts, I assume you may be trading SPX. Be aware that you will pay exchange fees here with IB, that can be as high as an additional .77 per contract. This is the case with most brokers, except Think or Swim, which generally quotes an "all in" price, so they can be substantially less in single listed products such as SPX.
If you are trading options spreads, IB might "hold" them internally until they feel they are marketable. Big disadvantage here as they are often wrong here.
IB makes it difficult to direct a spread to a specific exchange, all though it can be done. This can be useful as your fills on certain exchanges may be better than others.
IB gives you access to almost every product, which is great. They are the only retail broker that gives you access to the overnight session in SPX and VIX options.
Overall their commissions are very competitive.
There customer service is hit or miss. Long potential wait times and you may or may not get a competent rep.
To me their biggest knock is their auto liquidation program. Since it is not done manually, the computer makes decisions that can be extremely negative, on what, when and how they liquidate.
