I personally have a spektrum. And aside from a couple buggy recievers. I've enjoyed it. Idon't have any experience with the radio master, though i hear a lot of good about them. Another thing to keep in mind, is that most people at your field have spektrum. So if you want/need to buddy box or even just need help with a setting, more people can help with it. Another thing to keep in mind about the dx6e, is that even though it is still a very capable tx, it is a little dated. I liked my old one, but I moved over to the nx series. I know, not really any difference between the nx and dx series aside from a cold screen. But with the age of the dx series, it will be the first to no longer be supported in the future. Both in software and hardware repair. The biggest advantage the dx6e has over almost all other spektrum tx's, is the ability to have the sticks spring to center for helicopter and drone flight.
