Noob bracelet are becoming shitty. There is nothing to compare finish quality between arf and noob.
Take your finger and move it between noob link connections and you will see that it's not smooth.
Probably noob started to rush through the finishing process to increase production.
ARF feels smooth and edges are deburred even in the inside parts where you can not feel it. These small details put together what makes the bracelet closer to gen.
This being said, the match between the sels is a hit and miss. I have arf bracelet on my noob case, but i have switched the the SELs and put the noob sel on arf..
And of course the clasp. Arf is much better.. I spend 1/3 of the time to genify the ARF than noob.
Much solid and less machining marks to remove
Edit:
Regarding the gen like feeling. Its almost impossible to achieve that without removing and taking apart the single links to its bare elements, cleaning and lubricating connecting pins and replacing the inner link tubes to a tiny bit larger tubes.
Gen uses almost friction fit tube/link combo. That's why when you move the gen links and play with it you feel super solid connection between links, there is absolutely no play between gen tube/link connections.
