Its a good question. I guess its about familiarity. Never tried Starlink, but I have use sat phones in the jungles of Colombia and Tanzania. Given that this is a US centric vehicle, you make a good point.
Starlink has been working in many countries around the world without issue, even in countries where they list that it doesn't work. They touched on this in a recent episode of the Overland Journal Podcast. Combine the Starlink with your cell phone for wifi calling at basecamp/around and in the vehicle along with full internet capability and then use your inReach on your person when away from the vehicle.
