They are both fantastic strollers for everyday use, on-the-go errand running, big city and urban usage, and also for traveling, especially airline travel.
The Traveler (XLC) is designed to be the very best travel stroller on the market, while also your everyday stroller! It fits in virtually all airplane overhead bins as carry on luggage and is also fully loaded with features which make it a fantastic normal usage compact lightweight stroller.
The Tour+ (XL1) is designed to be the very best everyday, on the go, super lightweight, compact, and fully featured stroller on the market. It also has the unique capability of expanding to become a full tandem (front to back) stroller. It comes with a belly bar, parent cup holder, child snack cup holder, and child drink cup holder. It really is packed with just about every luxury and creature comfort that Zoe offers!
So both strollers are fantastic for everyday use AND travel use, but each model is slightly titled towards one or the other.
If you'll primarily use your Zoe stroller for traveling, you should probably choose The Traveler (XLC). If you'll primarily use your Zoe stroller for everyday usage with some occasional travel, and would like to potentially expand to a tandem stroller, you should probably choose The Tour+ (XL1). With that said, you really cannot make the wrong choice between these two strollers. They are both exceptional in each use case!
