I only use chain with a come along.
Straps suck for winches and comealongs, they just stretch in a slow scary sort of way. Chains work well with HiLift pulling too. I rarely use a HiLift but have one just in case.
When pulling someone out of the mud or snow we use snatch straps. I use 2 at a time in case one snaps. I've snapped 3 before doubling them up, none since.
I cut the hooks off and just use 3/4" dia shackle bolts through both straps. Sucks to have a hook fall off into the mud.
I'd stay clear of any cable, chain,strap, rope whatever under tension. Anything can break at any time no matter how strong it is.
Sometimes the tow points just simply fail,things happen.
