Actually, I like both equally but they serve different functions in our house. I don't like carrying petflys one outside because it looks like a duffel bag, and doesn't have any place where I can carry my wallet and cell phone safely. But, I really like its stucture and design. Especially when we are traveling it is perfect.
Since petflys one has the side opening, it also doubles as my Chi's "den" in the house. We leave it open in the study, and he goes in it to take naps when he wants his alone time. I would definitely recommend it.
