Both devices use a Pancake Geiger tube. GQ tells you its GMC-600 uses a LND7317 tube, but Radeye stays suspiciously mum on the origin of the tube.
However, as Radey says its tube has a 44mm diameter window, chances are that both device use the very same tube manufactured by LND!
Even if their tubes were different, there is no way that a tube of same size can produce any different result!
So, with the key element of a Geiger counter being the same, it makes you wonder why the GMC-600 costs 400€, while the Radey costs 2400€.
I am hard pressed to see an extra value of 2000€. (But obviously, when you are able to purchase that device, you don't pay for it yourself, but use taxpayer's money!)
But since you say to have "zero experience" I suggest to go for a GMC-800 instead. Once you understand what you are doing, you will know whether you even need a (more fragile) pancake detector.
