So after how many tens of hundreds of hours in Skyrim, I just now took the Shield Charge perk. Well, let me tell you this perk is ridiculous! Bodies go flying everywhere, nothing resists it (even enemies that can't be knocked down are still heavily staggered), it takes no more stamina than normal sprinting, and completely overpowered!
It's also totally hilarious and fun! For now. I can imagine it becoming tedious soon. For now, it's awesome when you're charging a bandit marauder, he attempts a power attack, time slows down and BOOM! Baddy goes flying in slow motion.
Overall, I guess it's a good prize for getting Block, one of the slowest leveling skills (sans exploits), all the way to 100!
