Has anyone used RG Series rails?

Question

3D printers

Hello.
Tell me who had experience using the rails of the RG series or the HG series (the first are four-row rollers, the second are four-row balls)
The idea is to put a hiwin RG or similar on the X axis, HG 2pcs. put on the Z axis in coreXY.
Or is the game not worth the candle and is it better to just buy good quality MG rails?
