Both makers publish a power rating. Lake People G111 Mk II publishes at 32 Ω, at 300 Ω and at 600 Ω; Schiit Valhalla 3 at 32 Ω and at 300 Ω. The other rows are worked out from those.
So the two columns are not equally firm row by row: at 600 Ω only the Lake People G111 Mk II figure is the maker’s own. On those rows the derived number is the one to doubt first.
1 headphone reaches 100 dB on the Lake People G111 Mk II but not on the Schiit Valhalla 3 — Symphonium Titan.
535 headphones are left alone by the Lake People G111 Mk II under the one-eighth rule but coloured by the Schiit Valhalla 3 (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 532 more).
14 headphones stay below the audible-hiss threshold on the Schiit Valhalla 3 but cross it on the Lake People G111 Mk II (64 Audio Aspire 1, 64 Audio Ocean, AFUL Explorer, 11 more).
566 of the 567 models here reach 100 dB on both.
Headroom is at a 100 dB SPL peak.
The widest gap on the list is the Audio-Technica ATH-R70X: Lake People G111 Mk II has +27 dB of headroom there against +20 dB. 7 dB is about 4.5 times the power, which matters for peaks rather than for how loud the music sits.
Hiss below about 20 dB SPL is inaudible in a quiet room.

The Lake People G111 Mk II costs $130 more than the Schiit Valhalla 3. Out of the 567 models here, that difference buys 1 more model driven to 100 dB and 535 more models left alone under the one-eighth rule.
It does not run one way only: the cheaper Schiit Valhalla 3 keeps 14 models below the audible-hiss threshold that the Lake People G111 Mk II does not, which is the part worth checking against your own headphones before paying the difference.
