I'm thinking the difference going from 28 to 25 will be much bigger compared to going from 25 to 23.
I'd say you're going to notice a huge difference, but even with roads not smooth I think 25s should still be reasonably comfortable.
Just don't go to 22s
Today's groupride:
Distance: 85km
Duration: 2h47m.
Avg. speed: 30,5 km/h.
We rode varying terrain, so a lot of small short climbs here and there. We rode up the Thier D'Amry, which is a short climb. 300m, 11% avg. gradient, 18,9% max gradient.
The recordholder on Strava did this in 39s at 30 km/h! That has to be close to a 1000W!
