The Spektrum radio is a name brand with more sophisticated features and probably has much better build quality. Any radio with 6 or more channels would work, and it really comes down to how much you want to spend and if you're going to use it for other models too. FlySky stuff is pretty good for the price, also look at an i6S for a nicer form factor. I use an FrSky Taranis for drones and hopefully a work in progress tank project. It doesn't come with a receiver but is a really popular choice with a build quality closer to Spektrum.
