If it matters any, you'll probably end up doing more shifting with 4.10's, and you'll be shifting out of 1st before you clear the intersection coming off a traffic light or STOP sign. 5th will be somewhat more responsive and hence more useful, 1st a lot less so (and going WOT in it may become just an idle daydream). Around town mpg shouldn't change much, steady-speed highway mpg may drop a little. That 55 mph will probably help hold the amount of mpg loss to a minimum. You'd be geared very close to where I was in another car with shorter tires, 3.73's, and daily driven.
3.73's aren't enough different from the 3.55's that you should have to be worth changing to unless you have some unusual requirement for reaching a certain speed in a particular gear. It's only 5% different, and clearly noticeable change in lots of car performance stuff happens when the changes are at least 10%.
"Don't fear the gear" is not a reason. Just pressure from others to blindly choose without thinking.
