Impossible to say, as you're not comparing like with like. This is hugely impressive, but is definitively continental, ie dry-tooling steep limestone to access hanging ice-formations, just without the bolts.
Harder than on-sighting The Hurting in a blizzard, with slopey ledges and hooks that need to be cleared, gear that may not hold and a fall that may not be survivable? Who can say..
