Need actual owners experience on which 1 ton to buy.

So would those be Rambulances then?? Lol
To OP, ANY of those will perform similarly and well for a LONG time.

My preference would be 2, 1, 3 in that order......but even though I've been a Mopar/GM guy forever, the new SD Fords are awesome and I've generally had good service out of the 20 or so Ford work trucks I've had over the years.

Anecdotally, I'd also take the engines in the same order for reasons already mentioned.
