UR Princess Longji has higher attack cap (29999) than GSR Uriel (24999), and has a larger buff. Uriel's buff being non-element doesn't mean much if you're not putting attack arcanas into every card on your team which is very expensive and mostly wasteful. You're better off stacking it into one card (i.e. Princess Longji).

And yes, skill unleash will give your cards extra procs that they normally wouldn't have. Maxed attack cards with maxed building and other bonuses only need a couple buffs to tap for 999999 damage.
