Which tote/messenger bag is better for high school?

[Katherine]

I'm going to be a freshman in high school next year, and i found a few totes/backpacks i liked and I was wondering which would be good practicality, size and style wise. Also, if you think the messenger bag or tote style if better for high school. Thanks! Here are the pictures of the ones I like:

And also I would love if you could say which you like or don't like, or which you like best. I would love if you posted some bags you like or think would be better! And do you think for high school with lockers if these will fit my stuff and if messenger bags or totes would be more comfortable. Thanks!
