If your movement feels gritty it probably needs a servicing. That's hit or miss with reps, I have plenty that are running well with smooth crown operation years after purchase including several VR3185s.
The VR3185/6 movements are generally rock solid movements and are far and away the top tier rep Rolex GMT movements available. The hands wobble that occurs during hour jumping is a byproduct of the 3185 design and the gen 3185 exhibits the exact same characteristic. The gen 3186 was developed specifically to eliminate this issue but the re-design resulted in a weaker jump click part. Rolex has had to update the part twice and is now using the third version in the 3186.
Gen jumping hour click springs compared
There are two versions of the VR GMT movement, both are based on the gen 3185 so RWI decided to call the first one the VR3185. The only difference in the second version is a fake deco plate on the balance assembly to make it look like a gen balance. And the regulator arms were moved to the opposite side. Both are engraved 3186.
The hands wobble exhibited on these VR rep movements should be accepted as welcome confirmation that you have the best movement. The other Rolex rep GMT movements (2824 CHS, SA3186, SH3186, SA3285 are vastly inferior by comparison and should be avoided.
The CF bezel assemblies are indeed a significant shortcoming and at its price we should certainly expect better. GMF, VRF, ROF, and some other bezels are much better but every rep has its flaws so we have to pick our poison.
I currently have a couple dozen GMT reps including two CFs and rate them close to the top of the heap for what's currently available OOTB. Prices are climbing for all reps so are they worth the money? Probably not, but few are anymore.
Even the highly touted VSF Sub 41 has a couple of real downer flaws - the SEL mid link definition is noticeably slight and the cyclops has obscene edge distortion. But I have a couple of those too and place them close to the top of the heap as well.

"Love em for what they are and don't hate em for what they're not" keeps me happy in my fantasy land. That's all this hobby is after all.
