It's not very often that a cover song improves on the original version. But sometimes I find covers that I prefer to the original.
Naglfar - Dawn of eternity (Originally by Massacre on "From Beyond")
It must be the production that does it because this is so much heavier and brutal on Naglfar's version.
Dark Fortress - Endtime (Originally by Katatonia on Brave murder day)
I don't know what they did to it, but it's longer than the original and just better.
Emperor - Cromlech (Originally by Darkthrone on Soulside Journey)
The production does it again, plus they play it faster. A great song made even better.
I could go on but now I want to hear your suggestions.
