Prophet = 210D UHMWPE
HMG = 150D Polyester on a cuben base.
I'd say they'd approach each other in toughness, but the MLD pack can only handle 15kg but the HMG can take 25kg (but it is heavier).
I think Forest has had his Arc blast for a while and might be able to give more abrasion resistance details.
To clarify, the 210D refers to the weight/strength of the coloured Nylon fibres that make up most of the "Dyneema X" fabric. Only the white ripstop grid is actually Dyneema or UHWMPE. I'm sure you know this already but in case others are confused it is definitely not pure woven dyneema. Such fabrics exist but are rare and stupidly expensive. That said, I use a daypack I made out of Dyneema X and it's been great. I have no worries about scraping up against rocks that would destroy a sil-nylon daypack in seconds. Possibly the perfect low-cost, low-weight pack fabric (hence why I chose it).
150D polyester face fabric doesn't sound that tough when you consider "tough" nylons are 500D to 1000D or more. I definitely would not go throwing my HMG pack around on rocks too often but it would probably stand up to infrequent moderate hauling. Also being laminated to the extremely strong cuben fibre underneath would increase its overall toughness (but not its pure abrasion resistance).
