I've traded with GAIN, MG, & FXCM and CMS. By far CMS has been the best for spread, leverage, paying interest, and no re-quoting. MG & FXCM are classic re-quoters. Try to enter in fast market conditions and I guarantee you will be re-quoted at a price other than what their system is publishing. It happens everyday and many times 3-4 pips or worse! With GAIN I only have this problem about 1 out of 10 trades. I like GAIN and have used them for about a year but I have experienced too many trades were they've come off the bid taking out my stop only to return to the bid. In addition, not that I typically trade during the Asian session but I was last Wednesday night and watched GAIN post 6-7 PIP spreads in the Dollar/Swissy & Pound/Dollar. Now I understand it was thin market conditions but CMS was firm at 3 pips in the majors. I like CMS's trading platform over the others also.
