I know that we say にっぽん instead of にほん when we want to inject a little
national pride into the word, but I've never had a good understanding of the
difference in meaning/nuance/usage between やはり and やっぱり.

I would guess that there is some variation in some combination of politeness,
formality, familiarity etc, but I haven't had enough experiences with them to
pin down where they sit on that graph.

question
nuances
What's the difference in usage and nuance between やはり and やっぱり?
やっぱり「矢っ張り」 is a bit stronger in sense than やはり「矢張り」, but most of the time, it
is a personal preference.

There are some more versions of やはり like

やっぱし、やっぺし、やっぴし、and also やっぱ is widely used.

answer
やはり is more formal (e.g. appropriate for superiors & business). People say
やっぱり all the time, including in business.

Written scholarly works would most certainly use やはり. Shibuya gals would most
certainly use やっぱり. There's a wide range in between.
