Short term purchase, I would say Jeti. They have had more time to develop a larger ecosystem of hardware and software
Longer term, PowerBox. They simply need more time to develop software features and add hardware accessories
I started with Kraft in the 70’s, switched to Futaba PCM single and dual stick in the 80’s and aboutb4 years ago bought 2 Jeti Tx (DC16 and DC24 and too many Rx, ESC and telemetry items to count!)
I am confident my next purchase will be Powerbox Core... I think it’s a better long term investment and a better hardware platform.
