Just went through this myself.  I've used (and still have accounts with)TD Ameritrade, Tradestation, and IB.  TDA has a very good mobile platform but their executions and commissions are terrible ($2.25 + exchange fees[another$1.19]=$3.44/lot  for ES  futures as well as the pleasure of the platform freezing when it gets really busy).  Tradestation is an excellent product for charting and programming.  I have some IRA accounts with them. Their options platform is rather good and  their fees are better than TDA.  However, you CANNOT trade options on futures from the main platform.  You have to have a separate Futures+ account which is web-based and terrible and not attached to your equity account.  I think TS is $1.25or $1.50/lot +exchange fees.  I recently moved to IB (in September) and think its great.  $.80+$1.24=$2.04/lot for ES futures plus volume rebates.  Don't love their mobile platform for options or their charts but definitely the most professional desktop product and the fees can't be beat.  Hope this helps!!
