Biking dedicated GPS are organically designed to make it easy to create a route or multiple routes on Garmin or third party and get those routes onto the device very easily. If you need to transfer .gpx files to a hiking model, which I don't know how well that works and is a bit more work involved every day. My preference is an Edge with good battery life like a 1040. OTOH, I have followed a couple doing a cross USA as well as cross France who used a generic Android phone and Kamoots. The phone had an external battery for supplemental power. This seemed to work very well for them, so it's a good option it seems.
