I haven't seen the latest products or production, so my comments in this context may well be malapropos, but the Cvstos pieces I have seen are acceptable and interesting if inextricably tied to the qualifier, "for their price." But remove that qualifier context, and I would hardly compare the CLASSICAL (ie, using classical standards) finishing levels with PP or Lange; not even AP or VC. Certainly not KV or PD.
RM models (especially their "entry level" models based on Vaucher movements) essentially sidesteps this issue entirely - there is no "classical finishing" (whereas the Cvstos pieces I've seen do, even in the pieces depicted in this thread - bevels, edges, large expanses of flat surfaces with graining, etc.)
So comparing the two is a bit of a red herring, in my very humble opinion...(obviously I don't imply an "intention" with that red herring comment...)
