I think Hughes just had his 2nd international start, and to compare him to any of the others is a bit harsh at this point. He was England's best heavy carrier against France, and pretty much the only one to make a few yards when being the first man to hit up slow ball, even though he was targeted like hell. As soon as we got some extra carriers on the pitch, he was no longer getting marked so heavily, and started making more serious yards.
Picamoles also carries a huge amount on the wings, which tends to be a bit easier to make ground in than the dark places we were sending Hughes into. But there again, France had enough heavy carriers near the breakdown that they could afford to do it.
I think we are also a bit too ready to look at BV now, rather than BV of a few seasons ago. Even now, Billy's quieter games inevitably come when he's the only good carrier in the pack, generally when his brother is missing basically, and this has been true for seasons.
I think Clifford is a bit more dynamic than Wood, but I'm not sure about his heavy carrying, even then, he's at least another Launchbury/Itoje carrier, which is an upgrade. Launchbury was actually making some good damaging runs when he went for it, typically the phase after Hughes had just wrapped up 3 defenders (he was often quick at presenting the ball too, which helped offset Youngs a bit).
Right now Hughes is inexperienced at this level, but even so, I'd consider him over Strauss and Heaslip (please note consider, not definitely take).
His general workrate in the France game seemed better too, he was covering ground a bit more freely (think he had a thigh injury in the AI's no?).
Is he as good as BV, of course not, but it's unfair to compare him to the BV of today, especially to the BV that had Mako (another very good carrier), Haskell (a half decent carrier) and Robshaw (an acceptable carrier) starting with him, rather than Wood, Lawes and Marler (fresh back from a broken leg). Lawes in particular was embarrassing, getting stopped by one tackle, and sort of folded in half, whilst going backwards by the second tackler.
