Long time android/gmail user, and I always use the Gmail app.
however I tested out the samsung app when I got my note2 and you know what? It has some features that make it hard to go back to gmail app.
Advantages of Samsung App
---------------------------
HUGE- can spellcheck (i had auto spellcheck in gmail app on galaxy nexus but not on my note2)
HUGE- can change font color and size, can draw pictures...lots of text options
Split screen on landscape (like tablet)
multi tasking on split screen (verizon)
better appearing conversation view
spen integration
Disadvantages
--------------
not push for gmail
Cannot get DRAFTS folder to sync (so a draft stays on phone-cant continue on cpu)
difficult to look in folders past sync date limit
labeled email not colored
overall still using the samsung app because of the advantages.
