IMO there is nothing better than a beautiful early morning hike. Cholla trail definitely delivered.
The degree of difficulty will vary obviously depending on your hiking experience, fitness level and personal preference of which type of hike you enjoy.
With that being said, I don't believe Cholla Trail is easier than Echo Canyon. The hike is could be considered easier if you stop at the heli pad. If you continue to the top of the summit where Echo Canyon and Cholla meet then it is significantly more challenging.
Echo Canyon is no walk in the park but I would recommend it over the Cholla Trail for those new to hiking or not as experienced.
