I haven't listened to enough stuff but I'll have a go. Some of these opinions are pretty biased.
10 Snakes Pure Evil
A fun and memorable groove act. Full of character not nearly as try-hard as most of the other entries on this list. Really catchy with some interesting songwriting ideas and structures thrown around.
9 Rivers Of Nihil Where Owls Know My Name
Stands out among a lot of progressive death metal due to riff ideas and dynamics that often seem to remind me more of indy rock than any of the styles that progressive DM often borrow from.
8 Psycroptic As The Kingdom Drowns
Some interesting twisted riffing ideas that are somehow simultaneously instantly catchy. Higher energy with more jerky and exiting song structures than their last release.
7 Inertia Tetroma
It's rare for me to like a djent album so these guys were working against a pretty hefty handicap. Techy and occasionally sour this album has some ridiculous noody riffs and sounds that endeared it to me on first listening. Uapologetically jazzy for significant chunks.
6 Requiem And The Earth Grew Dark
An Ararat (Victoria, Australia) band who have gotten exponentially better with each release their third album. Effortlessly combines the agression of high-speed death-thrash band metal with the some of the darkness of a blackmetal release. Clearly taking some inspiration from Aussie blackened prog metallers Hybrid Nightmares (alongside whom they performed in 2017) in this release the riffing and solos reach a new high while also showing enough restraint to let the vocals cement themselves in the listener's mind. As much as en enjoyed this album, I can't help but wonder how much better the next album is going to be.
5 Aborted TerrorVision
Experimenting with more interesting time signatures and song segments than any other release of theirs I've heard, Aborted add tech to the list of death metal sub genres in which they flirt with without entirely surrendering to.
4 Whoretopsy Take My Breath Away
Checking these guys out after hearing about their unfortunate censorship at a couple of venues (Cannibal Corpse effect in full swing, take THAT society!) I was amazed to hear how characterful a slam band could be. With an array of interesting riffs with an odd sense of melody and groove and song structures that evolve seamlessly; slams are used somewhat sparingly and to great effect, often emphasizing a critical point in one of the album's disgustingly beautiful stories.
3 Golgothan Remains Perverse Offerings to the Void
Australian dissonant DM with high impact moments scattered throughout sour landscapes of sound. Ugly howling vocals and a warm, modest (but not forcibly so) production add to the album's charm.
2 Serocs The Phobos/Demos Suite
Dissonant, aggressive, melodic, brutal. This murky album varies from bleeding arpeggios to high impact churning groove riffing to aggressive patches that rip your face off while keeping a sense of sophistication throughout the experience.
1 Hadal Maw Charlatan
Was there ever a contest? With some almost linear song structures that pull you spiraling into a murky void and a rougher production, this EP is considerably less listener friendly than either of their previous efforts but somehow even more characterful and memorable.
