For the sake of comparison, let's assume that we always have access to Fracture and Soul Cleave. If there are 3 or more mobs, Soul Cleave = ~350k per hit x 3 hits = 1,110k damage for 60 pain, and takes 1 GCD. For the next 2 GCD, you cast Shear/Sever for ~190k avg, totaling ~1.5m. Fracture x3 would be ~250k per hit x6 hits = 1.5mil damage. With Cleave you're at 20 Pain, but with Fracture you're at 0, so you have to spend at least 2 more Shear to get back to catch back up. So for damage output, 3 targets is a slight edge to Soul Cleave, without considering any other talents in the row. This also doesn't take into account the ability to squeeze that single cast of Cleave into the final second of Razor Spikes damage buff, where Fracture would not get full benefit from casting all three. Considering other talents in the row, Feed the Demon will grant higher up-time of Demon Spikes, leading to higher damage reduction and extending your up-time of 30% physical damage buff.
For mitigation/survival, I think that you'd find it very difficult to find much support for Fracture providing more mitigation. You can look at Mythic Krosus as an example and just check people who run Feed the Demon vs Fracture to see how much external healing they require. I don't want to detract from Fracture's usefulness for Single-Target damage output, where it does have its uses, but in Mythic+, AoE is king.
