used both, although there are rooms for improvement. For now, my votes go to Garmin ... life saver at least for me at times that i am lost..

Used both Garmin and Papago on seperate smartphones. IMO i prefer Garmin's voice navigation seems like more simple for me. And the directions on the map, at least for me i still can figure it out and did not got lost on Garmin. While for Papago, the voice commands seems to be long and repeating for me, i got confused sometimes.

though the Papago interactive maps looks better and cooler, but i still prefer the simple and clean commands from Garmin. I am using Garmin on my phone and Papago in my car HU unit.
