The quality of Garmin's 100k topo varies, but in many places the street data is terrible. Here's an example (in Toms River NJ) from City Navigator, and the streets are pretty accurate

Compare this to US Topo. The streets are off by almost 3 blocks here as well

Garmin's 24k topo should be better. My understanding is that it uses Navteq street data, which should look like the streets in the City Navigator example above. I have never used the Garmin 24k topo maps myself, so I really can't say though...
