I was on the fence with my SS 38mm. I liked it a lot but thought I would prefer the larger screen and font sizes on the 42mm so I returned my 38mm Watch. I just got the SS 42mm Watch and could not be happier. It really does not feel any bigger on my (165mm) wrist but the screen is much easier to read. Even typing in the password is much easier and I think I will enjoy the battery which supposedly is bigger in the 42mm. I would say I think the 38mm looks better when the screen is off (it is a smaller slab of black glass and looks less like a smartwatch which is a good thing) but I definitely prefer the 42mm overall. But its not for everyone and I am glad we have choices.
