I'm going to unbury this thread as I've noticed that my Note 3 (bought at 10 March 2014, so probably a recent built) takes considerably more pressure to activate the digitizer on the bottom right, pretty much above the speaker.
This is noticeable for instance on the . key on the Samsung keyboard. Apply the same light pressure as on other keys and nothing happens. Push it harder and it triggers. This becomes quite annoying while typing with the pen, especially for people coming from the N2.
If you like to use your fingers you'll be OK. No difference at all.
