Others encountered on my search:

Seems like each has its merits. I am going to demo choice one stocktickr since it will mark my trades for me on the chart. (a time consuming task I do every night) and also has many different ways to look at results. It appears they integrate multiple accounts as well. They also have you tube tutorails which help me understand a new work flow faster.
Hope this is helpful.
