Is galaxy note worth galaxy s2?

I am interested in buying galaxy note and I am switching from galaxy s2.Should I do this?What you guys would better prefer because I have heard alot of laaging problems with the galaxy note was that on gingerbread or still the lagging is on ice cream sandwich?And I received the jelly bean update official for my galaxy s2 and I also heard that galaxy note Jelly bean update is near.Is that already on the galaxy note?
