FlashoverPassive

EradicationPassive

Soul Fire4 sec cast

Flashover - this talent is always your choice until you can get the 4 piece due to other talents not being efficient enough and the Cinders legendary being your bis choice without tier set.

Eradication - this talent gains much more value once you acquire the tier set, allowing you to cast much more chaos bolts and will become your best choice in every situation.

Soul fire - is just unplayable and very bad in any way possible. Unfortunately, it has a very long cast time, low damage.

Reverse EntropyPassive

Internal CombustionPassive

ShadowburnInstant

Reverse Entropy - the best choice for any kind of content, haste is your best stat, procs often enough, and your rotation doesn't change. It's overall a great talent.

Internal Combustion - very single target focused talent, and you would need lots of haste to make this work. It doesn't look like a good choice in the current patch.

Shadowburn - can be a decent choice if the encounter type consists of many waves where mobs die consistently, like m+ or Rygelon. It looks less appealing once you get the tier set because you are less starving with shards and probably want to spend your globals on chaos bolt or rain of fire more than on SB.

Demon SkinPassive

Burning RushInstant

Dark PactInstant

You can use either Demon Skin, Burning Rush or Dark Pact. All 3 are viable for different situations.

Demon Skin is great if you’re stacking up a lot and taking constant damage with not much movement in the fight.

Burning Rush is great when there is a lot of movement and you need to help with mechanics or dodging certain mechanics. 

Dark Pact is a great option when you need to soak heavy damage; however, you need to make sure you use this ability when you’re at full health to get the full effects as the damage absorbed is based on current health.

InfernoPassive

Fire and BrimstonePassive

Cataclysm2 sec cast

Cataclysm - your best choice on fights with 1 to 2 targets.

Fire and Brimstone - Currently doesn’t do enough damage to compete with other talents.

Inferno - might be a good choice for m+ with consistent heavy pulls with a lot of adds. Especially if combined with RoC talent and Wilfred’s legendary.

DarkfuryPassive

Mortal CoilInstant

Howl of TerrorInstant

Dark Fury - reduces the cooldown of your stun and increases its radius, it can come in handy sometimes, but most of the time, it's not needed.

Mortal Coil - Pretty much the only viable talent in this row for m+ and raiding or PvP. Don’t forget that you can use it during havoc window to CC two targets and not one.

Howl of Terror - May come in handy for PvP in certain situations.

Roaring BlazePassive

Rain of ChaosPassive

Grimoire of SacrificeInstant

Roaring Blaze - This talent is pretty strong in single target scenarios without the tier set, and you will most certainly want to be playing Cinders with this.

Rain of Chaos - This is a very strong talent for AoE situations and greatly combines with Wilfred’s legendary. Also, your best talent in a row for any situation with 4-piece.

Grimoire of Sacrifice - pretty weak talent compared to the other two.

Soul ConduitPassive

Channel DemonfireChanneled

Dark Soul: InstabilityInstant

Soul Conduit - This is a solid choice for consistent AoE in mythic+ without tier set and your best talent in any situation with a tier set.

Channel Demonfire - is currently losing to other talents in its value but can be a good option for very low m+ where everything dies extremely fast.

Dark Soul: Instability - without tier set, it’s your best talent for single target and cleave, but once you get your set, it’ll become a niche talent for fights with phases of increased damage taken like LoD or Anduin.
