Regarding GMT movements, I suggest reading
GMT Movements Explained to understand them better and learn how to recognize what is being offered.
There are so far only 3 true 3185/6 clones being offered, listed here in order of best to worst
VRF - VR3185 based on VR3135
ARF - SH3186 based on SH3135
GMF - SA3186 based on SA3135
Not coincidentally the 3135 movements these GMTs are based on are also ranked in the same order of best to worst.
There are many other threads discussing the pros and cons of 3135 movements, it is general knowledge that the SA3135 commonly used by BP/GMF and Noob among others, is the least preferred of the available clone 3135s.

The Noob CHS A3186 timebomb is a modified 2824. Noob has not offered a true clone 3186 as of yet.
There are only three model releases with true clone movements. 116710LN, BLNR, and 116713LN.
Factories and dealers often call the 2824 CHS an "A3186", this is misleading and they are not true clones like the others. Looking at the movement pics will confirm this.
