Best is so subjective. The best for me may be the worst for you.
What is your budget? You can spend from about $30.00 dollars US to a couple thousand dollars.
The Taranis is a nice radio. There is a learning curve to ti but there are a lot of youtube videos on how to set it up plus a couple goof forums. I have Airtronics and FrySky. I do like my 9x. Budget priced and tons of features.
