You'll have to make the call on that. I have both, and like both. I like the RX better, frankly. It's smaller, about the same weight, gets twice or three times the battery life and was easier to set up in TC. I didn't get the Koopor Plus running properly in SS mode until I input the TCR code for 316 wire (which happens to be .00092). I also find the RX is more ergonomic and fits my hands better. Comparatively, the Koopor is like vaping a brick. That said, there's nothing wrong with the Koopor. It's a very nice mod and I like it. But if I could have only one, I'd pick the RX.
