well I guess it depends on the individual.
If you have a crazy Jungle going on, that's exposed even when you have your arms down by your side than by all means trim or shave.

If like most men, your armpit hair is never exposed than why bother?

I'm no caveman, I trim and at times am completely smooth south. That's because I want someone's face there.
Likewise I appreciate and expect her to at least trim or be completely smooth.

How often though are you gonna find a gal ready to sink her face into your armpits?
