Nope.
I suggest him to avoid cherry profile for dat he isn't changing fullset. It will be weird to mix both oem stock keycaps with cherry profile.
Regarding the POM part, some chinaboards (namely keycool, kbc and plu) are having tight POM. The ok one is rare, such as official cherry or plum's one.
In his condition, he seeking for blank cap, which so far the ok one (POM) didn't offer (except you manage to special order official cherry one unprinted). As he is still beginner, so I suggested him to simply avoid it.
For the vortex RGB, yar the printing sucks, but at least, it is still pbt, which is far superior than most oem boards' offer.
So in short, my suggestion is valid enough. I gave suggestion based on his requirements and needs, rather than suggesting what is the best he can get.
Somehow I agree with this.. it takes time to explain all those things that only some of us would understand... so better off give them the balance of the best of what they want instead of what we think the best
