Fell Cleave: 520p for 50g; 10,2ppg
Inner Beast: 350p for 50g; 7ppg**
* = if HP at 100% and no HP boosting buffs active
** = simply added for comparison in less-than-ideal scenarios
So Upheaval has full dibs on gauge priority, followed by FC / IB. Onslaught is best used as a gap closer to increase uptime if for some unfortunate reason walking between GCDs isn't enough when you eventually have to do a bee line for mechanics. Alternatively its decent for snap aggro in fights with adds that start with 0 enmity along wizh Equilibrium. Also affected by Unchained, if you need a lot enmity FAST.
