As above, I found it to scale better with mastery than CB, because outside of CB+Meta's extreme burst window, Demonic has more use of it. Even with Chaos Cleave CB, around 25% of your damage is non-chaos, while it's sub15% for Demonic. That shifts drastically once you get AotHG, and I've mentioned that Demonic is stronger without it, but not as strong with it.
Of course Chaos damage % out of total damage doesn't mean a lot when you flat out get 30%+ total damage during CB. The reason why Demonic benefits it more is because Annihilation is stronger than CS, and you get to cast Annihilation almost 3 times as much as you would with a CC-CB build ( 163.0 vs 56.4 on average in my latest sims, raddons + cinidaria, no tier).
As for tier set bonus, Demonic scales better with it than the other 2 builds (First Blood CB and CC-CB) since it casts Chaos Strike/Annihilation the most out of these three. Both Demon Blades and Demonic Appetite cause your crit value to get higher, you simply have a different reason for it (less downtime for DB, more fragments for DA which is directly tied to Meta uptime).
But, as I said many times, the difference in sims is marginal (FB-CB pulling ahead without tier by about 1-2%, Demonic being 1-2% stronger than CC-CB with tier, and CC-CB being the strongest with AotHG, surpassing Demonic by about 2%, and leaving FB-CB in the dirt). This is player playstyle choice right here. The major difference between them is that CB offers you massive burst windows every 2 minutes, whereas Demonic grants you sustain and more sustained damage. Both have their applications, but I'll probably be playing Demonic in all situations, mostly because I like the theme.
