Delightful MM, Totally Mm or Neverfull MM?

I want to get a bag before the price increase (was hoping there wouldn't be one before Feb. 6 when we will bein Las Vegas). I live a very casual lifestyle and want a shoulder bag to use everyday. I have a Rivington GM that I love but want something mono this time. Suggestions, please!
 
I just got the GM NF Mono for that very reason. I have the Sully MM and it's beautiful but for everyday running doing errands and down the shore I wanted a no worry bag. I treated the handles and leather trim and I should be good. If your worried about security I also bought a zipper purse organizer.
