CTDolan, an interesting assertion. I tend to agree with you to a degree. BUT... 
Superior design means little without superior performance. If all we're discussing here is engineered design superiority of the cartridge, maybe we're done??? Well... Maybe, maybe not.
The Ruger is pretty much a ballistic twin to the H&H so exterior ballistic performance is pretty much a wash. The Ruger fits in a standard length action so that may be a check in the Ruger column.
On the flip side Ruger is STILL replacing Alaskan's in both .375 & .416 Ruger due to feeding issues. I would suggest the design of the Ruger cartridge may in fact be inferior from the feeding and ejection standpoint. Of course, one could argue that this is dependent on the gun/manufacturer... Still, tough to beat that long taper and small, shallow angle shoulder and smaller body diameter of the H&H.
Switching gears a little, I'd suggest that anything the .375 Ruger or .416 Ruger can do, the .416 Rem Mag can do better. Even though the cartridge design itself may be "inferior" (belted and long action) I would most likely choose a .416 Rem Mag and/or a .375 H&H over either of the Rugers.
I really like both of the Ruger cartridges and I would own either one or both. Just not over the H&H or the .416 Rem. So strictly from an engineering standpoint, maybe the Ruger's are better. But from the performance standpoint there are cartridges that are superior to them both. So is the design really superior? Depends on how you define "superior".
I guess that puts me happily in the RedLegVeloDog camp
That is, if they'll have me 
Cheers amigo
