Thule vs Osprey travel backpacks

I've been researching various bags to use while travelling for 8 weeks & had found/thought I'd go with Osprey (40l fairview with my own personal bag or the 55l one with detachable day bag) but now I've been informed about Thule & I'm curious to get thoughts and personal recommendations one way or the other?

These are two options I have Thule Womens Landmark 40L Backpack or Thule Womens Landmark 60L Travel Pack

What would folks recommend more? For context I'll be travelling in South America and North America.
