From a pure snow total standpoint, going to be hard for any storm to top January 2015 for me. 33" of snow under that death band. 34" wouldn't do it, would take a storm dumping 3' on me to even consider it.
From an experience standpoint, the prolonged nuclear thundersnow of 12/9/05 will always be tops. Walking home from school in the middle of the road because that was only spot remotely passable with numerous CGs booming around will never be topped.
