depends, if you are gonna get a WRm V10 Ferrocore, then you should get that. If you are gonna get the standard V10, get the RS3M V5. I can’t really say anything about the YS3M though (i heard it’s blocky)
ill probably get the RS3M V5 just because I'm not trying to spend $40 on a cube (WRM V10 Ferrocore is $40)
