Favorite brands of RC equipment, is very much like politics, you will find people who like JR, Futaba, Airtronics, Spektrum, FrSky, and any other brand out there.
I have seen every size of plane from indoor to IMAC's flown with almost all brands.
I myself fly JR because I like the "feel" of the transmitter in my hands, I am VERY happy with JR.
All brands can use any size of servo's and Rx's, so they will all fly any size of plane.
When you get into large scale planes, then you may need more channels than most of the systems in your price range. One big exception to this is the FrSky Taranis, I have friends that have them and are happy with them.
You may get a better Tx if you look at gently used ones.
