Let me re-emphasize my point that it would be amazing to see a hockey prospect whose untrained athletic ability is at the level of a Walker but is more sport-specific to hockey.
Having said that, I would argue strenuously that, all hockey skills being roughly equal (speed, balance, agility, hands, vision, hockey sense, grit), the 6'1" guy who can bench 350 lbs. would be a more effective hockey player than 6'1" guy who can only bench 150 lbs.
And don't say the much stronger guy would surely be bulkier and therefore slower and less fluid, because there probably isn't a starting wide receiver in the NFL who can't bench over 300 lbs., and many can bench over 350.
