Amen. Chains are only my preference, but then I'm known to be a little hidebound, stubborn (if not outright mulish), and stuck on some old ways that were handed down to me. Still, I'll use properly-rated straps in good condition if that's what my load calls for.
The "good condition" part is important. Straps can be weakened by knicking and chafing, UV damage . . . But it's not unheard of for a load to be red-tagged for stretched chains, either.
You've hit it on the head, John. Either will do the job while satisfying the regs.
