If you can do it, I think you should get the ST. As far as I know the ST comes with every option, maybe even the massage seats and other things that if you're driving 250K, you'll want in the truck.

I had a 2017 Explorer XLT with a 3.5 NA V6 and just over one year ago I moved up to the 2020 Explorer ST. There is no comparison, the Explorer has the 3.0 Turbo which is a new motor for that year. I have about 16K on the truck and it's been awesome. Ford Performance really stepped up with this offering, it's like a domestic BMW X5 for much less cost.

The 2.7 eco is now the standard motor in the Ford F150, they dropped the N/A V6 altogether. It's plenty enough for an F150, even hauling an open trailer. I only went 3.5 eco because I tow an enclosed trailer. Almost all my friends except for one all have the 2.7 eco and they love it hands down.

The 2.0 Ecoboost I think is the upgraded motor for the Escape, it prolly does fine in an Edge, but if you can get an ST......doooooo it.
