Overall it's a tough call, I've gotten a lot of playtime out of a decent number of albums. If I had to choose one, I really really enjoyed Skylar Spence - Prom King. Much more than I expected. Some other Honorable Mentions that I spent a good amount of time listening to that no one will care about:
Arca - Mutant
Cherubs - 2 Ynfynyty
Jacek Sienkiewicz - Drifting
Neon Indian - VEGA INTL. Night School
Pinkshinyultrablast - Everything Else Matters
Lightning Bolt - Fantasy Empire
Oneohtrix Point Never - Garden Of Delete
To be perfectly honest though, this year has been much much better for Electronic EPs, I got a lot more listens and enjoyment out of them than most of the albums I listened to this year. My EP of the year is Hidden Spheres - Waiting. There are plenty of other fantastic EPs this year tho, like:
DAZE - Neuromance
Galcher Lustwerk - Parlay
Four Tet - Morning/Evening
Martyn Hare - Enter With Force
Octo Octa - More Times
Zeitgeber - Monad XX
Honestly I'd rate the EPs as better than the Albums this year, which is a surprise.
