I am trying to choose between these two bags.

I am biking less and less because I mostly transit these days but I find a messenger bag great as I can swing it around without taking it off on the train. I also really dislike messenger bags that hang by the hip, I must prefer a bag that can cinch tight on the back. Currently have an old chrome metropolis and looking to downsize.

I am looking for a comfortable strap (please dont say to get a two strap bag) and a nice place for my laptop.

I am worried about the roll top of the mission rummy. I really like just using velcro to keep the flap closed on my chrome but this is mainly to quickly get my laptop in and out of the bag. I think I can access the laptop pocket in the rummy with the top still rolled up but not sure about the pocket for the laptop on the rummy to be honest.

The seagull looks nice and its cool that I can customize the colours and get a laptop sleeve built in.

Price is about the same so not a big issue on that front.

Suggestions please
