Put the Exped Ultra 3R next to the Big Agnes Q-Core SLX and the trade-offs are clear. The Ultra 3R wins on low weight and warmth-to-weight, and the Q-Core SLX pushes back on packability and cushion.

The Ultra 3R is 1 oz lighter and stronger on warmth-to-weight. The Q-Core SLX is more packable (1.6 L vs 2.2 L) and thicker for more cushion. On the default GearScore the Ultra 3R leads 77 to 74.
