I just looked at the prices and fetures of the Futaba 7ch and the Spektrum 7ch radios, if I was on the market for a new radio I would go with the Futaba, buying 8 channels or more will cost you a lot more.
All the top brand radios are good ( I have used them all in the past ) I was looking for a new radio about 6 months ago and end up buying a Futaba 10CAP from the for sale here on RCU ( got an excellent deal for it ) my previous radio was a Futaba 9CAP that I used for about 12 years without any problems, the 10CAP was the most logical next step to get since I know the sofeware well and I love the big screen, I also prefer the round dial instead of the turning barrel ( I also have a Spektrum 6iX )
My recomendation, if in the next 2 years you are going to fly sport airplanes only then get a 7 ch but if you think you want to fly more sofisticated airplanes then get a radio with 8 or more channels.
I hope this helps.
Good luck.
