[Q] Do different nibs function differently? topic

I lost the nibs to my Note 4 almost as soon as I got it, so I am wondering if the replacement nibs have different functions. I know the Note 3 pen had replacement nibs that were identical to the one that was pre-installed, but I heard some suggestions that the note 4 had nibs with different feels (rubbery vs plastic, etc). I know there are wacom nibs out there with different textures, so I'm not sure how the note 4 is.

Do any of you still have your extra nibs? Have you tried different ones to see what they're like?
