Perhaps for the professional riders who do grand tours -- the trade-off will be road grip/stability and comfort over a period of days' races. The 25's will work on most kinds of road surfaces and still grip well on fast descents.
Anyone who is not racing and doing a 2 hour ride (duration) will also let out some air from the tires.
