I use OptionHouse, which I do not see mentioned here very often. I have only been trading Options for about 4 months and do not have experience with other brokers. So far happy with OH and their customer service....
I just went to the eOption web site and their commission structure is very good, better then I have. Could not see what their platform looks like or its functionality.
So I called them up to ask about their platform.... told I had to open and account to see it... They did say I could see the platform before I fund my acct.
I do not have the time to play that game, so I said good-bye.
Also am considering moving to IB.. better commissions then what I have now... I hear their platform is also not so user friendly, but their fills are very good. Looks like I can save about 50% on my commissons at IB. Maybe 100 contracts a month using credit spreads
Have not looked at Trade Monster....
