THE SHORT ANSWER
The Cloudsurfer 2 is the lighter shoe by 0.9 oz in a men's US 9, and the drop is within 1 mm (10 mm on the Pegasus 42, 9 mm on the Cloudsurfer 2), so it is the one that feels quicker without asking your stride to change. Both sit in the same role (daily trainer). The Pegasus 42 lists $15 lower.

Which line changes its ride more often?
Both lines rework the ride about as often: the Pegasus has done it once in 6 versions, most recently with the Pegasus 41 in 2024, and the Cloudsurfer has done it once in 2 versions, most recently with the Cloudsurfer 2 in 2025. Neither is the safer long-term rebuy on this record.
