It's hard to compare Mesa Arch in the Canyonlands with Delicate Arch in Arches National Park since they are entirely different. However, while Delicate Arch is a moderate hike of 3.2 miles, Mesa Arch is an easy hike of just 0.5 miles round trip. So if you can visit just one of these two arches, Mesa Arch is much easier to reach than Delicate Arch.
