Ive never been a fan of LG, so my opinion is somewhat biased.
I do bounce between notes and the motorola droids and have since the note2.
Touchwiz has gotten better over the last couple years, to the point there really isn't a reason i can find to complain about it.
Samsung has evolved the software so that it is easy for beginners, and pleasing for people who know Touchwiz and android.
Its just a matter of taste, but it doesn't hurt to try it. For me, i like the stuff built in to the latest Samsungs, part of it is the newer versions of android and part of it is Samsung's take on trying to make a good phone experience.
Good luck, and hope you enjoy it, but you can always go back if you want.
