There may be other ancillary benefits, but size alone, come on,, folks!
Yes. It makes a difference. For me the move from 700c to 650b began as a way to fit a 47 mm tire onto a frame designed for 32mm. Since then I've come to appreciate the balance in proportion between frame size, tire diameter, and my own body height.
Riders distinguish between frame sizes sometimes in 2 cm increments such as from 54 cm to 56 cm. Right? So it's perfectly reasonable to choose between tire diameters in the same manner. In an ideal world, tire diameter and frame size would both change and be in proportion up and down the range of sizes.
