Famous quote
Better to beg for forgiveness than ask for a permission
I have both Turnigy 9X and Taranis X9+. Taranis has more memory, voice feedback, OpenTX companion, more features fit into memory, SD-card slot for logging/models/graphics, USB connection either for flashing, PC connection or you can use it as a controller when flying simulator. Parts for Taranis are easy to order, and it's such a popular radio with open-source firmware so you can find lots of youtube movies how to set it up etc...
When it comes to design, it's plastic, with same cheap plastic gimbals as Turnigy (better is hard to say), for this price range you should not expect Jedi or Multiplex quality. It's still low-budget transmitter. New Horus should be better built
http://www.frsky-rc.com/product/pro.php?pro_id=144 but that's way higher price range and no open-source OpenTX firmware which is a bummer. Also for Jeti it seems you need to pay for every extra functionality and receivers are big.
Taranis is not a beauty when it comes to look (though you can order cases with different patterns), but has been and still is the best price to features transmitter.
