I've transitioned through a couple different styles and will be using their new classic (vertical) layout.
Here's the flex or horizontal layout from 2015:
In 2016, I switched to the A5 inserts, which only came in the flex or horizontal layout. I'm a big fan of carrying extra stuff in my planner, like bills, stamps, coupons, or any important papers, which didn't work too well in the bound planner. The A5 binder has worked really well!
Here's a preview of the A5 classic (vertical) layout for 2017. Visually, the classic flows better in my mind, so this is great! I get the best of both worlds with the A5 inserts and the layout. I'm glad the hours have been left unlabeled- I'll use the bottom portion of each day to track my Etsy shop and the top will be more of the 9-5 hourly schedule for appointments, etc.
