Does tube size matter?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Got a couple of spare tubes and notice they are marked as 19/23. I usually get the 23/25 as I run 25 tires. Is this really gonna matter enough that I should swap 'em out?

My girlfriend says size doesn't matter, but I think she is just being nice to me.

I use 19-23 on a cx bike with 34's on it. Haven't noticed any problems.

They will be easier to mount and somewhat lighter. They might also be slightly easier to puncture, but really the last thing you should rely on for avoiding punctures is tough tubes.
