I guess I didn't get the memo that posting sets wasn't allowed at this time, so I'll just try to summarize what Snorlax has to work with. Facade hits a hell of a lot harder against neutral targets than Gliscor's EQ. Snorlax also has defensive boosting options like Curse, Amnesia, and Stockpile which Gliscor doesn't have. Oh, and just for reference:
0 Atk Gliscor Earthquake vs. 252 HP / 252+ Def Snorlax: 97-115 (18.5 - 21.9%) -- possibly the worst move ever
0 Atk Snorlax Facade (140 BP) vs. 252 HP / 252+ Def Gliscor: 102-120 (28.8 - 33.8%) -- possible 5HKO after Poison Heal
So Snorlax is at least beating Gliscor at its own game.
As for the weakness to Fighting types:
252 SpA Keldeo Secret Sword vs. 252 HP / 252+ Def Snorlax: 260-308 (49.6 - 58.7%) -- 14.8% chance to 2HKO after Poison Heal
If Snorlax gets a Curse or Stockpile off of a free switch, it is going to be very difficult for the opponent to break through especially now that status is not an option against Snorlax. I could see Curse + Protect working very well in this physically dominated metagame. I really do believe that Poison Heal Snorlax has the potential to really shake up OU if it gets voted for.
