That's a great cover version, BTW. Thanks for posting the link.
To my ears, the studio version is predominantly the B-octave part over the G/Bm chorus section. Listening to stems I found via google, there appears to be two parts - the octave part that can be clearly heard, and the "live" part of G to Bm power chords, though the latter is mixed very low in the studio version.
My preference is to play this, which is a hybrid of the two parts:
During the 2 bars of G:
|--x----
|--0----
|--4----
|--x----
|--2----
|--3----
During the Bm and F# bars:
|--x-------------------------
|--0--------------x--x--x--
|--4--------------5--6--5--
|--4--------------x--x--x--
|--2--------------3--4--3--
|-----------------------------
Although not strictly speaking "correct", IMO it sounds faithful to the studio version but retains the heaviness of the live version. YMMV, etc.
