The remote version was harder for me because:
RC makes up a larger portion; not only did I do significantly better on LR, my 2nd LR was almost always better than my first (more warmed up, I guess).
I enjoy walking into a testing environment and feeling pressure to perform in that space. It's just not as easy to get adrenaline/energy up alone in the area I've been captive in for hundreds of days.
Reading on-screen can be an issue. Tracking with a finger on paper helps improve reading speed. Someone also quoted me that reading on screen is 33% slower on average. Circle back to point 1.
Chime in with your own reasons (disagreeing is ok, too!)!
