It took me a long time and a lot of research to decide .. but I went with FXCM which are also one of the largest brokers and so far (3 months) I am satisfied with them, particularly customer service. I have a service rep named Tangie and she answers my emails promptly, I can always reach her by phone if necessary, and the service in general is friendly and upbeat. My experience with them has been a positive one. No problems on the trade side either, the spreads are within reason, the executions seem to be as fast as anywhere else, the only drawback, they did not have the MT4 platform, but they will have it this month.
I preferred using a MT4 platform from another broker (Interbank) just to double check the quotes, so I am not particularly concerned whether they use MT4 or not. I love theor trading platform for executions, I prefer it to MT4. (MT4 is best for charting)
Hope that helps & doesn't further confuse
